[mythtv-users] No audio in MythTV, where to start ?

[Anders Pedersen]

Hi

I've the "No Audio" problem with MythTV and I don't know where to start.

I've "googled" around a lot without any luck. The problem is there is to
many parameters to "mess around" with:

* There is the .asoundrc file
* There is the amixer settings
* There is the Gnome audio settings
* There is the mythfroentend audio settings

Can someone please help me in the right direction so I can solve the
problem step by step insted of gessing and just changing parameters
"with the eyes closed".

Best regards
Anders

Here is some info:

The TVCard is: Avermedia (FM1216ME). The card is set up as number 22 and
the tuner is 38.

The sound card is SoundBlaster Live 5.1.

The two cards is connected with a cable. If the cable from the TVCard is
connected to speackers I got sound, buth not in MythTv.
This command make me watch TV in mplayer:
mplayer tv:// -tv
driver=v4l2:norm=PAL:input=0:amode=1:width=384:height=288:outfmt=yv12:device=/dev/video0:chanlist=europe-west:channel=K62

Before starting mythfroentend this script is executed:

[mythtv at localhost ~]$ more amixer_initiate.sh
amixer set Master,0 75%,75% unmute
amixer set PCM,0 75%,75% unmute
amixer set Line,0 75%,75% mute captur
amixer set Capture,0 75%,75% captur
aplay /usr/share/sounds/startup3.wav

The .asoundrc file is like this:

[mythtv at localhost ~]$ more .asoundrc
pcm.emu10k1 {
type hw
card 0
rate 32000
}

ctl.emu10k1 {
type hw
card 0
rate 32000
}

Here is the AUDIO settings in the mythfroentend:

Sound: ALSA:default
Output device: ALSA:ice958:{ AES0 0x02 }
Mixer: default, PCM


In the Gnome sound settings "things" is like this:

Sound Events, sound playback: autodetect
Music and Movies, sound playback: autodetect
Audio conferenving, Sound playback:Autodetect, Sound capture: SA7134 PCM
Default mixer tracks device: SB LIVE 5.1 (Alsaq mixer), CAPTURE

The gnome sound software (ESD) is disabled.


When I start the mythfrontend I get this info:
