l3mce....   I didnt make any adjustment to xorg.conf... only /usr/share/alsa/alsa.conf and /etc/pluto/xine.conf


You might need to take a break from programming 

Dennis

yay!

l3mce,

by only editing the following lines in /usr/share/alsa/alsa.conf, I have surround  (Dolby Digital and DTS) thru my HDMI:

Code:

#
# defaults.ctl.card 0
defaults.ctl.card NVidia
# defaults.pcm.card 0
defaults.pcm.card NVidia
# defaults.pcm.device 0
defaults.pcm.device 7

and this in /etc/pluto/xine.conf:

Code:

audio.device.alsa_passthrough_device:asym_hdmi

without the added line in xine.conf, lmce displays a message that it cannot play the audio track (or something like that).

The reason I did this is because the HDMI audio is NOT card 0 in my system.. but is card 1 (NVidia) as listed by cat /proc/asound/cards.

Should it be possible to get DTS-HD and True-HD from the .mkv files (they have the HD audio in them)?

Dennis

rough work aint it?!!??!??...


Thanks for being able to do it (and doing so)...


Dennis

not a problem... Im really 'experimenting' to see what will or will not work... and maybe something I 'stumble' upon can give you a hint.

Dennis

I did get a little bit (band-aid perhaps) further.  I did install linux-image 2.6.38-16-generic which gave me the HDMI audio devices. Installed linux-backports-modules-alsa-lucid-generic, then backed up /etc/asound.conf and /usr/pluto/templates/asound.conf, then copied /usr/pluto/templates/asound.conf.backports to replace the other two.  Running AVWizard didnt give me any sound, however I am getting HDMI sound with Mythtv, but not with dvd images.

Dennis

got it... Im back to that... but back to where I was at the beginning.   

with the default linux-image of 2.6.32, the NVIDIA HDMI ports will not show up:

Code:

and asound reports only one card:

                      HDA ATI SB at 0xf7ff4000 irq 16
root@moon53:~#

with alsa backports installed, the card is reported by asound, but not with aplay -l:

Code:

root@moon53:~# cat /proc/asound/cards

                      HDA ATI SB at 0xf7ff4000 irq 16

which one is required?  or both?... or am i going to need to use a newer kernel?

Dennis

l3mce,
    per your instructions I modified the following files after the initial build of the MD image but before the MD booted into it:

1. modify nvidia-install.sh putting the PCIID for my card in the correct spots (my card ID is 1244)
2. modify AVWizard_Run.sh

Then starting the MD up, am getting a Failed to Set Up X  message.   Here is dmesg reports for NVIDIA:

nvidia-glx-260 fails to load.

according to this page - http://www.nvidia.com/object/linux-display-ia32-260.19.29-driver.html, the GTX 550 Ti is Not supported.   The earliest found supporting the GTX 550 Ti is here - http://www.nvidia.com/object/linux-display-ia32-275.28-driver.html



thanks,
Dennis

Ive not been able to work on this for the past several days... my job is just nutz right now.... sometimes working 18+ hour days.

I'll try this again this weekend.

Dennis

l3mce...   it is a rainy day here... too muddy to do any work outside... so I got some time.

can you post what I need to 'modify' in nvidia-install.sh? 

I can tell you that with the stock kernel,  alsa does not even see the HDMI audio stuff... even if I install the backports-modules-alsa for the kernel.

I do know that once a 2.6.35 or greater kernel is installed, the audio hardware is seen by alsa.


So... Ive already upgraded today.  Ive rerun Diskless_CreateTBZ.sh... and am standing-by for further instructions!!!!


Dennis

l3mce,
     I'm going to rebuild my MD (with the GeForce GTX 550 Ti) this weekend and see if ithe fixes work for me.

Dennis

in mythtv setup, are there channels listed under Channel Editor?

if so, check to see if the 'starting channel' is a valid channel on the Input Connections screen for the input of the hdpvr you are using.

I'm running an HDPVR with a satellite box... there is a tunetochannel.sh script in /usr/pluto/bin that can change channels if youve got a sat box that has a template.


I am assuming you have a core/hybrid and you are not on an MD...   if you are on a separate MD, ive found there is always a discrepancy with the uid of mythtv.


Dennis

Worked on this after work today...

the nVidia GTX 550 Ti card (audio portion) will not show up unless a kernel >= 2.6.35 is running...  I tried the alsa backport modules.. but no change.


okay.. running a kernel that allows me to see the nvidia card audio..    
1.   modifying the nvidia-install.sh has no affect other than making the AVWizard start on every boot.... the end result is still having the 304.43 driver installed.
2.   modifying the AVWizard_Run.sh script has no affect other than unmuting the card 1, device 7 channel.  No AVWizard sounds are heard

Im gonna give it a rest for tonight...

Im thinking I might try running a live-cd of kubuntu 12.04 and see if HDMI audio works there...

Any more thoughts l3mce?


Dennis

I'll give that a shot tomorrow after work... gonna relax and just watch a movie before bed (and while laundry is finishing). 

Dennis

l3mce,
here is output you requested:

Code:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] [10de:1244] (rev a1)

I did not find the pci id 1244 in nvidia_install.sh.    I did find this http://www.pcidatabase.com/vendor_details.php?id=606 and found id 1244 down at the bottom in the table 'Pending new devices for this vendor'.

On MD creation, the nvidia driver 304.43 is being installed.

[    2.106758] uvesafb: NVIDIA Corporation, GF106B Board - 10500000, Chip Rev   , OEM: NVIDIA, VBE v3.0

[   23.507329] NVRM: loading NVIDIA UNIX x86 Kernel Module  304.43  Sun Aug 19 20:20:21 PDT 2012

will give the mod to AVWizard_Run.sh a try.


Thanks very much for your hard work,

Dennis
