CX23880 Analogue TV Tuner, cannot be recognized by MythTV/LinuxMCE?

[ferdies]

Hi,

Kword TV Tuner has been installed and looks like it has been autodetected. However, MythTV cannot recognize it.

Is there any driver I still need to load?  Appreciate the assistance

Below are some of the details:

I have tried to use:

modprobe -v cx88xx card=48

(since my card is a Kworld MCE 200 Deluxe), but still I cant solve this problem.
Thanks.

Additional information:

I also have checked if the modules are loaded, and it looks like they are:

----------------------------------

Anything else I need to do / check.

Everytime I select TV, a screen will show up that myhttv will do the pre-scaling.  Then followed by a BLANK screen, after 30-secs or so, it will just go back to the MCE main screen.

Thanks.

Almost there......

Finally able to load the driver.

I think it is the bug of Ubuntu, as per this site
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/115719

Thus, I did a force module load

I edited "options" in /etc/modprobe.d

and added:
options cx88xx card=48

I was successfull in loading the driver.

My only next problem is the BLANK SCREEN --- whew! been doing this for so many hours..am already tired 

[seth]

 
I had to manually set a card with this chipset up in mythtv. I had an AverMedia 150M. Same chipset, same messages. But you just choose a v4l device in mythtv set and set it to your /dev/videoX number, and then I got it to work. It is just a frame grabber, but can be used if manually set up. Sarah did not know it was even there.

Just my experience.

Seth

My Linuxmce already recognized my tv tuner. I setup in MythTVbackend Analogue V4l tuner and, video0 (in my case). I was able to scan all the channels.  However, if I am in Linux MCE, and selecting TV -- it will just be a blank screen, and after few seconds, it will just go back to the main Linux mce screen.

Any idea why?

[seth]

Is this your only tuner? Or are there others?

[ferdies]

Yup, I only have 1 tuner at this point in time.

[ferdies]

I have 1 PCI with sound capability and 1 HDA on-board sound.

1. HDA-Intel
2. Sound ouput of CX23880

What's so confusing is that cx88_also still keeps appearing. I think this is very related so my MythTV sound problem since it is trying to use cx88_alsa -- but I want my MythTV to use HDA-Intel.

Hi,

Appreciate if you can help advise on how to stopping loading cx88_alsa...this module has a lot of conflict and suspecting causing my MythTV to not use the spdif.

Any idea on how to turn off this module...This is all related to snd...

I also have tried:

sudo modprobe cx88_alsa

but get this error message:

inuxmce@dcerouter:/etc/udev/rules.d$ sudo modprobe cx88_alsa
[sudo] password for linuxmce:
FATAL: Error inserting cx88_alsa (/lib/modules/2.6.22-14-generic/kernel/drivers/media/video/cx88/cx88-alsa.ko): Unknown symbol in module, or unknown parameter (see dmesg)


Thanks.

[seth]

You could try blacklisting the module in

Code: [Select]

/etc/modules.d/blacklist
Edit that file and add the cx88_alsa in there, reboot and see what happens.
This will prevent kubuntu form loading that particular module.

Thanks, the above did not load cx88_alsa. However, my problem of no sound ONLY in MythTV Live TV exists. My DVD, CD, music, and other sounds are doing all ok...but MYTHTV Live TV.

Hopefully someone can help...I have tried everything -- but all the suggestions from these sites were not successful for me.
