[SOLVED] debian wheezy only mythtv has sound

Quakeboy02 · 06-19-2013, 08:31 PM

New squeezy install, and the sound is only partially working. It's just fine viewing a video in mythtv. But no sound with mplayer, etc. Also, when I capture from /dev/video directly to a file (e.g. cat /dev/video > test.ts) I don't hear any sound on playback. However, copying that same file to my old faithful squeeze, on another system, the sound is fine. I notice that wheezy is using faac for sound, while squeeze is using faad on the same file. Any help would be appreciated.

Do you have more than one sound card? If yes this may help: https://bbs.archlinux.org/viewtopic....997335#p997335

Nope, just one sound card.

Is there any other way I can test this or get some more data points? Mythtv sound works OK. It's just odd.

Here is the output from running mythfrontend in a terminal. I did notice that when I start a video there is a distinct pop as the audio is enabled. Notice that pulseaudio is suspended and audioplayer is enabled. Could that be an indication of what's happening? I know nothing about pulseaudio. Is there some setup I need to do, or do I need to somehow setup something else as a default audio handler?

Hmm, I found another thread on this, and the following post seems to have fixed it, once I killed pulse. I'll play around with it some more and see what I can see.

http://www.linuxquestions.org/questi...9/#post4618029

Code:

I edited /etc/pulse/default.pa and uncommented two rows:
Code:

load-module module-alsa-sink
load-module module-alsa-source device=hw:0,0

If you also have pavucontrol it sets up pulse.

Quakeboy02 · 06-21-2013, 02:24 PM

Thanks for the heads up. It's strange that Debian would ship a distro that doesn't work until it's been worked over. Oh well. It's certainly not your fault. Thanks for the help! If I hadn't pulled that output I'd never have noticed the problem was related to pulse.
