Intel HDA Audio - No sound: With a Twist!
My laptop, with the Intel HDA ICH 7 audio controller is not outputting any sound, usually. I am running the 18.104.22.168 kernel with sound support compiled as modules. The card seems to be working fine (the relevant modules are loaded, it appears in alsaconf and alsamixer, but no sound is output, usually. As far as I can tell (I am running madplay with a known good mp3 file to test), the sound card will only output sound for one command after bootup. If I, say, ctrl-c out of the program and start it again, I get no sound. I can understand sound not working, but this inconsistent pedrformance is really irritating me.
Where would I find relevant error messages?
Should I download the newest ALSA drivers?
Is there some other arcane magic that might be invoked to get this sound card running properly?
I will gladly provide any more information that might be useful.
see Software mixing section
look for the digital output setting
theres a good chance either something is muted or digital output is enabled.
My onboard hda Intel i had to mute/unmute a few channels.
Cant remember the titles all i remember was there was 2 front left and 2 front rights
1 of each had to be muted before i got it worjking
