I am almost ready to put my system in the living room and when I plugged speakers in I noticed I had no audio.

Not sure if it was the PVR 250 not getting the audio, or something else, I downloaded an MP3 and tried playing it with mplayer. No audio there either. Tried all the ports on the sound card.

Sound is onboard on the compaq desktop I have. It seems to be detecting ok and mplayer isn't reporting any problem opening it etc.

Is it possible it is muted somewhere? Any ideas on how to test/confirm audio?

Thanks.

lsmod | grep snd
See anything? Run aumix and turn it up...

It appears to be an intel 8x0 card...

alsamixer says its:

Intel 82801DB-ICH4
Analog Devices AD1981A

I ran aumix and turned it up (volume was already at 70%). Still no dice... Also tried playing a CD from within Myth, still no audio. :S

Argh...

I just combed through the output of dmesg twice and I'm not seeing a sound device detect, but I'm also not certain what I should be looking for. Can someone steer me in the right direction? Maybe its not detecting at boot... :S

you probably need to make sure your output channel is unmuted, not just turned up.

Also make sure you try unmuting & turning up the "Surround" channel. I have an ICH5 system and the surround volume control is the only one that seems to have any effect. I can mute the master volume and I still hear the surround channel!

Hi Jeff,

I have the exact same setup as you do, and I ran into the same problem. Check out the thread posted by reddog a few days earlier about recompiling msp3400. I did that and I got sound.

Hope that helps.
