PostPosted: Mon Aug 26, 2013 6:48 pm    Post subject: PVR 150 not capturing audio Reply with quote

last week, i had a older system running kernel 2.6 something and the two pvr 150 cards worked perfectly in it.

i just upgraded the machine, and did a fresh reinstall of everything. now, under the 3.8.13 kernel i can't get audio from the cards. i used genkernel, so i don't know precisely all of kernel settings that were enabled, and i'm not really able to compare the two configs. it also seemed to compile every single thing as a module, so lsmod is a mile long.

for what it's worth, here it is:

sound on the system works just fine - i can play other videos and audio on the computer - i just can't capture audio through the card itself.

trying to play a file the card captured appears that it's TRYING to get the audio, only muted?

Code:
# cat /dev/video0 > test0.mpg
$ mplayer test0.mpg
......
Playing test0.mpg.
........
==========================================================================
Requested audio codec family [mpg123] (afm=mpg123) not available.

........


and the video plays just fine. just no audio.

i've forgotten the myriad of ivtv-ctrl and v4l2-ctrl commands i've run, but all of them report the card (and tuner) to be "muted=0".

one thing that i find odd, is that under alsamixer, i get my normal soundcard's levels. but then with F6 i can select either of my IVTV0 or IVTV1 cards, but it says "This sound device does not have any controls.". i can't recall what the old system said, or if i could modify it there, but it doesn't seem right to me.

i've emerged the following:

any help? i assume it's just some kernel module i've not compiled and added? or some module alias or option i've not set?

ok, i just tried the mythbuntu (12.4 i think) livecd to test it out. i couldn't get the backend working (mysql wouldn't start), but i'm not 100% sure it can run a backend off the livecd. all the directions i saw wanted you to install it.

anyway, i booted the cd and dumped the /dev/video0 to a file:

$ cat /dev/video0 > test.mpg

and then played it on another computer. the video was all wonky, but there actually was sound!

this is, however, infuriating because i know it works somehow. i just downgraded my kernel to 3.4.55 (since that's closer to what the mythbuntu release was using. i copied the .config mythbuntu used and recompiled using that.

hopes were high, but the latest dump from the device still yielded no audio. just to ensure i wasn't crazy, i converted the file to a .wav using ffmpeg and played it in totem using one of their visualizers. it showed a flat line, whereas a known-good mpg converted the same way showed a jumpy line as expected.


does anybody have a working card that can send me their working .config? i'll just use whatever version you're using - hah.

tried a few more things and think i found the crux of the problem:

# v4l2-ctl --log-status

it seems that cx25840 can't detect audio from the coax?

i did some googling and found some threads talking about it, and the most promising one is this (though mine isn't fixed with a reboot - only by booting into mythbuntu):

but i don't really understand the solutions that were posted. how do i force the detection instead of letting it do it automatically?

muahhhahahaha! fixed it!

i didn't have "v4l-cx25840.fw" in /lib/firmware. i found a random copy of it, put it in there, then rebooted. worked perfectly.


it also looks like it might be in "media-tv/linuxtv-dvb-firmware", which is the proper way to do things, but the ebuild seems all jacked up.
