Ok.. I know these may sound really naive... but with the integrated audio thingies sometimes audio is really troublesome to set up even if everything is working correctly, so:Hi debian folks, I installed Debian last week (for the first time), and things generally went very nicely. One thing which isn't yet working though is sound. I'm currently using the kernel from debian-backports (linux-image-3.2.0-0.bpo.2-amd64) in order to get my ethernet working, but the same thing happenned with the stock 2.6 kernel too (linux-image-2.6.32-5-amd64) Any suggestions at all of things to try would be most appreciated. Below is hopefully relevant output from interesting commands.
- Are you 100% sure you have plugged your headphones/speakers in the right output. This may seem funny but here e.g. I have front and rear headphone jack and these are selectable from the alsamixer. I've seen situations in which only one worked so you should try the combinations. - On the same line try playing with levels and switches in (alsa)mixer (or some other gui version) .. I have seen that sometimes when I upgrade, for some unpredictable reason the PCM volume is turned down to 0 (PCM is basically all the audio you'll get from applications).
You would be surprised to know how many times I wasted time debugging audio problems at the driver level and the issue was actually in the (alsa) mixer, cables, plugs etc.
Good luck! Lorenzo.
