On friend of mine's KM R5D1 box I recently helped him upgrade from onboard audio to a Chaintech AV-710.

1. Disabled on board sound
2. Installed AV-710
3. audio device be set to /dev/adsp in Utilities/Setup -> Setup -> General, and both the AC3 and DTS options should be checked, with all others being unchecked.
4. Edited /etc/mplayer/mplayer.conf

5. Edited /etc/asound.conf

6. Ran commands


I get sound in MythMusic and MythVideo (mplayer). I don't get sound in TV, (recorded or live). I don't have any recordings post audio card install. The TV tuner is a Leadtek Winfast 2000XP VL4 card. The sound goes from audio out of tuner to audio input of AV-170 (blue jack).
The TV card worked fine with the onboard audio, and Tuner's VL4 config is set to /dev/dsp in MythTV's tuner config.

I messed around in alsamixer and unmuted everything and turned volume up.

I'm not against turning back on the onboard sound and using it's input, but don't want to make things worse by doing so as this system is remote.

This is full details of the hardware.

Thanks,

Edit: Card is connected to reciever via sp/dif optical.

Probably not the most correct fix, but moved the audio output of tuner to "Mic Input" and TV recordings now have sound.

same setup here. I used alsa. Does anyone know which is better?
only difference from default
/etc/mplayer/mplayer.conf



/etc/asound.conf



set general audio output device in myth to /dev/adsp
under video settings
default player is




My only problem is that sometimes my bios auto reset to defaults and the built in sound comes back on. Then I have to change to /dev/adsp2 and the mplayer settings no longer work. I have to change the asound.conf to reference hw:1,1. It still seems flip flop back and forth some times and i have to change it back...
