[mythtv-users] RE: nForce4 Audio on FC4, it plays some of the time....

Sorry about that, should be fixed now.  Just in case you still can't get it, here's the script in my KDE startup folder:

#alsafix.sh
sleep 5
amixer set 'Headphone Jack Sense' off
amixer set 'Master' 100% on
amixer set 'PCM' 100% on
amixer set 'Line' off
amixer set 'IEC958' on
amixer set 'IEC958 Playback AC97-SPSA' 100%

And here's my .asoundrc

# .asoundrc
# Override the default output used by ALSA.
# If you do not override the default, your default
# device is identical to the (unmixed) analog device
# shown below.  If you prefer mixed and/or digital
# output, uncomment the appropriate four lines below
# (only one slave.pcm line).
#pcm.!default {
#  type plug
## Uncomment the following to use mixed analog by default
#  slave.pcm "dmix-analog"
## Uncomment the following to use unmixed digital by default
#  slave.pcm "digital-hw"
## Uncomment the following to use mixed digital by default
#  slave.pcm "dmix-digital"
#}

	I had a very similar problem. I was finally able to figure out that KDE was messing with my alsa settings everytime it started, even when I told it not to. You can test this by opening up alsamixer and while your audio is playing, mess with the settings until you hear something.  I solved this problem by simply putting a script in KDE's /.Autostart folder, so after KDE starts, my mixer settings go back to the way I want them.  You can find more detail at http://www.dastrup.com/template_mythtv.asp and look in the Audio section.

Thanks James for replying,

I took your suggestions and tried messing with alsamixer while playing something, I never heard audio no matter what I tweaked.

I looked at your site and was going to look at your script and your .asoundrc, however I can't get to your FTP site. It just times out when I try to visit the FTP links. I tried from both work and home and I can't get to them. 

The program that opens by default when I double click the .au file is "Noatun". I can play the file all day long and it will sound just fine, however aplay still won't create audio.

Just for kicks I disabled the sound system in the KDE Control Center and rebooted, I was still able to play the sound from Noatun, but not with aplay.

Can you email me the scripts that you link to in the audio section of your website?

Thanks

Jason
