ASUS A8N-E on board audio. No audio output on AV wizard

[smitty1023]

Hello,

I have been trying to get th linuxmce up and running for 4 days now and slowly thing work until I have to reload and try something different to get things work. Don't get me wrong, its fustrating but at the same time I am learning a lot.

Anyhow I have video on the AV wizard, not out of the DVI yet, but no audio from the Strawberry Blonde during the installation. If I start the UI diagnostics tool I can hear the audio from the video of the flame thrower. Are the any special setups to get the audio?

[jetrich]

I too have the A8N-E and issues with the sound. Out-of-the-box the Realtek ALC850 chipset doesn't work (over S/PDIF anyways). I am attempting to compile enough useful information to post a fix for this board as it is rather irritating. For over a year I had a working KnoppMyth installation with this very board, _but_, I didn't document all the steps necessary to get it working. Live and learn I suppose. Hopefully I can post this information soon.

I will be reinstalling from the QuickStart DVD tonight, so perhaps in a few days I can have the fix compiled. Here's hoping.

I did get the sound partially working and will get the information posted as soon as I can. I have stereo output working through the optical out on the board, but have had no success with the AC3 pass-through. One step at a time. Just wanted to put in an update.

If you are using spdif make sure you unmute IEC958 in alasmixer settings.
run alsamixer from a terminal and press m to toggle the mute setting on IEC958


good luck

That, unfortunately, didn't get me anywhere with the out-of-the-box installation.

I needed to take a few extra steps to get the chipset to output through the spdif optical. Granted I only got the stereo output and no AC3 pass-through. However, http://wiki.linuxmce.org/index.php/Changing_Xine_Player_Audio_Settings might have some more useful information on how to circumvent the built-in xine commands. I'll have to pull my old working xine config file from the Knoppmyth install where this was all working fine. Accoding to the wiki: "M = Manual, if the flag is present, the whole configuration string will be ignored and defaults from /etc/pluto/xine.conf won't be overridden." Perhaps I need to take this step, but at least for now the sound is working, albeit without AC3.

/etc/asound.conf - from http://www.mythtv.org/wiki/index.php/Asoundrc_alc850

Code: [Select]

#~/.asoundrc or /etc/asound.conf
# ALSA configuration file

##### USAGE #####
# Save this file as "~/.asoundrc" (for user-specific sound configuration) or
# "/etc/asound.conf" (for system-wide sound configuration) and specify ALSA
# device names ad described in the next section.


##### DEVICE NAMES #####
# This configuration file defines four devices for use by the user.  Those
# devices are "analog", "mixed-analog", "digital", and "mixed-digital".  The
# user may also re-define "default" to be identical to one of the above-named
# devices (i.e. to send all sound output to the digital output unless otherwise
# specified).  Use the device names as described below:
#  - "analog" outputs to the analog output directly and (at least on software
#  sound cards) blocks other audio output.  After playback completes, "queued"
#  sounds are output in sequence.
#  - "mixed-analog" mixes audio output from multiple programs into the analog
#  output (so you can hear beeps, alerts, and other noises while playing back
#  an audio stream).
#  - "digital" outputs to the digital output directly.  Since most (all?)
#  digital outputs expect 48kHz PCM audio, this may not work for some playback
#  (i.e. CD's--which are 44.1kHz PCM audio--or 32kHz audio streams from TV
#  recordings, etc.).
#  - "mixed-digital"

# All other devices created within this file are used only by the configuration
# file itself and should /not/ be used directly.  In other words, do not use
# the devices "analog-hw", "dmix-analog", "digital-hw", or "dmix-digital".


##### IMPORTANT #####
# To make this ALSA configuration file work with your sound card, you will need
# to define the appropriate card and device information for the "analog-hw" and
# "digital-hw" devices below.  You can find the card and device information
# using "aplay -l".


##### Configuration File #####

# Override the default output used by ALSA.  If you do not override the
# default, your default device is identical to the (unmixed) "analog" device
# shown below.  If you prefer mixed and/or digital output, uncomment the
# appropriate four lines below (only one slave.pcm line).
#
# Note, also, that as of ALSA 1.0.9, "software" sound cards have been modified
# such that their default "default" device is identical to the "mixed-analog"
# device.  Whether using an ALSA version before or after 1.0.9, it does no harm
# and has no affect on performance to redefine the device (even if the
# redefinition does not change anything).  Also, by using this ALSA
# configuration file, you once again have access to unmixed analog output using
# the "analog" device.

# output on the card
# - Note that as of ALSA 1.0.9, "software" sound card definitions redefine
# "default" to do mixing, meaning this device is different from "default" and

I believe I restarted the machine here. Maybe just alsa but I'm not sure.

Then I entered the following commands in a terminal:

Code: [Select]

amixer set IEC958 unmute
amixer set 'IEC958 Playback AC97-SPSA' 0
amixer set 'IEC958 Playback Source' PCM
I pulled some other important info from these sites too:

I did place in /home/linuxmce/.xine/config the pass-through option (don't have that code in front of me), but obviously that didn't work.

Hopefully this information helps someone. I also figured that once we get this solved we can post this in the wiki so there won't be any more question on how to get this board working.

[tschak909]

looks like we need to add a soundcard setup script...

-Thom

[jetrich]

We should probably get some information from others using the CK804 and ALC850 chipsets to see if their hardware addresses for the optical can be automatically applied. I've read of differences (hw0,2 hw 0,0 hw 0,4 etc) between the cards that could be problematic. Or does this need to be applied to a broader range of cards that use the snd-intel8x0 driver. 

I'm willing to help out in any way I can, but I'm not a good "proper" scripter. I can usually hack something out, but that doesn't mean that it's good. 

Please let me know how I can help.

 Hi,

 I had this issue with different sound cards, i do not know if it helps with spdif but when this occurs i run
sudo alsaconf from a shell then i get sound on the standard stereo output of the soundcard.
 Then i run again the AVWizard and it all wroks fine

 Hope this helps,

Rafik

[jetrich]

I noticed that at some point my asound.conf got moved to asound.conf.pbackup, so I'm not sure what of the above has enabled the stereo output.

Here is what my asound.conf reads right now and the audio is still working as stereo sound.

Code: [Select]

pcm_slave.convert48k {
        pcm "spdif"
        rate 48000
}

pcm.spdif_playback {
        type plug
        slave convert48k
}

pcm.asym_spdif {
        type asym
        playback.pcm "spdif_playback"
        capture.pcm "plughw:0"
}
While perusing the source code on svn.charonmedia.org I noticed http://svn.charonmedia.org/trac.cgi/browser/vendor/pluto-lmce-branch/config-pkgs/intel8x0/mkr_postinst.sh is supposed to handle the creation of the asound.conf file that pluto should use. I honestly don't ever remember seeing that file in that format. Makes me wonder if that file will work correctly. Guess I'll have to try it along with the Manual configuration settings I mentioned earlier. Perhaps I can get to that this weekend sometime.

I have AC3 Pass Through working with this chipset right now (Aeon Flux in background)   

Check http://wiki.linuxmce.org/index.php/Sound_Cards for additional information. I need somebody to check my information and methods to verify that this is the best way to accomplish this.

Make sure that you have made the changes requested on the wiki page before proceeding with these instructions as the configuration file MAY be overwritten by pluto scripts if Manual is not specified.

Backup the original file and save the following to /etc/asound.state:

Backup the original file and save the following to /etc/asound.conf

Code: [Select]

# ~/.asoundrc or /etc/asound.conf
# ALSA configuration file

##### USAGE #####
# Save this file as "~/.asoundrc" (for user-specific sound configuration) or
# "/etc/asound.conf" (for system-wide sound configuration) and specify ALSA
# device names ad described in the next section.


##### DEVICE NAMES #####
# This configuration file defines four devices for use by the user.  Those
# devices are "analog", "mixed-analog", "digital", and "mixed-digital".  The
# user may also re-define "default" to be identical to one of the above-named
# devices (i.e. to send all sound output to the digital output unless otherwise
# specified).  Use the device names as described below:
#  - "analog" outputs to the analog output directly and (at least on software
#  sound cards) blocks other audio output.  After playback completes, "queued"
#  sounds are output in sequence.
#  - "mixed-analog" mixes audio output from multiple programs into the analog
#  output (so you can hear beeps, alerts, and other noises while playing back
#  an audio stream).
#  - "digital" outputs to the digital output directly.  Since most (all?)
#  digital outputs expect 48kHz PCM audio, this may not work for some playback
#  (i.e. CD's--which are 44.1kHz PCM audio--or 32kHz audio streams from TV
#  recordings, etc.).
#  - "mixed-digital"

# All other devices created within this file are used only by the configuration
# file itself and should /not/ be used directly.  In other words, do not use
# the devices "analog-hw", "dmix-analog", "digital-hw", or "dmix-digital".


##### IMPORTANT #####
# To make this ALSA configuration file work with your sound card, you will need
# to define the appropriate card and device information for the "analog-hw" and
# "digital-hw" devices below.  You can find the card and device information
# using "aplay -l".


##### Configuration File #####

# Override the default output used by ALSA.  If you do not override the
# default, your default device is identical to the (unmixed) "analog" device
# shown below.  If you prefer mixed and/or digital output, uncomment the
# appropriate four lines below (only one slave.pcm line).
#
# Note, also, that as of ALSA 1.0.9, "software" sound cards have been modified
# such that their default "default" device is identical to the "mixed-analog"
# device.  Whether using an ALSA version before or after 1.0.9, it does no harm
# and has no affect on performance to redefine the device (even if the
# redefinition does not change anything).  Also, by using this ALSA
# configuration file, you once again have access to unmixed analog output using
# the "analog" device.

# output on the card
# - Note that as of ALSA 1.0.9, "software" sound card definitions redefine
# "default" to do mixing, meaning this device is different from "default" and
# allows playback while blocking other sound sources (until playback

Make changes to /etc/pluto/xine.conf that are mentioned on the link above.

sudo /etc/init.d/alsa-utils restart
Then reload the router.

Not sure if these are still necessary as I already did them so it didn't get checked again:

Code: [Select]

amixer set IEC958 unmute
amixer set 'IEC958 Playback AC97-SPSA' 0
amixer set 'IEC958 Playback Source' PCM
Please somebody verify these as I'd like to get this finalized on the wiki as well. Any input on the proper formatting on the wiki page would also be appreciated.

Hi Jason

I have a Gigabyte K8NF-9 Mobo which has the same Realtek ALC850 chipset.
I can verify your method works with 2 exeptions:

1. On my system the ASOUND.STATE file is located at: /var/lib/alsa/
2. Ac3/DTS passthru works great on DVD's but for some reason it does'nt work on AVI's (works prefectly under vista ...)

Thnx for the great work and could you possibly look into the AVI thing ?

Thnx
Itsik

[jetrich]

Thanks for testing this.

I too have an asound.state file located at /var/lib/alsa/, however, I have not modified that file and it also has a modification date of "2008-02-24 20:00" which happens to be the last time I restarted the machine. I believe that the /etc/asound.state is used at boot to configure the /var/lib/alsa file. I could be wrong so please, if I am, somebody correct me.

The avi files I have played seem to send the DD signal correctly. I'll do some more checking though.

Also, what version of LMCE are you using? This was done under 0704.

Jason

[Itsik]

NP Jason.

I haven't found /etc/asound.state on my machine at all, I only have the one located under /var/lib/alsa/.

I'm using 0710B3

Itsik

[jetrich]

I had to _create_ /etc/asound.state with the information stated previously. Sorry if I neglected to mention that. Did you modify the /var/lib/alsa/asound.state file? If you didn't have to create the /etc/asound.state file it might be possible that some of this problem has been fixed in the 0710 release. Mine didn't work correctly until I created the /etc/asound.state file under 0704.

Jason

Regardng asound.state file: iirc, you can create it by calling "alsactl store", but the location will be different for different distributions (/var/lib/alsa/asound.state in Kubuntu 7.10)
