I have several systems with a TYAN S7025 motherboard and Realtek ALC262 chipset. I have not been able to produce any audio output. Well, that is except for one of the systems: after a variety of tweeks and tests, I got sound working on one system, but I do not know what change enabled sound to start working, and I have not been able to reproduce the effect on the other systems.
Can you give list of what tweeks you did (even incomplete).
I tried changing the 'model' setting several times, before reverting back to the default. I reran 'alsaconf' several times in the process, and occasionally noticed changes to the set of mixer elements listed by alsamixer. Sometimes a "PCM" element would be present, other times not. I also upgraded t the kernel from 2.6.31 to 2.6.32. While in 2.6.32, with the default 'model' setting (i.e. auto), I was in the alsamixer and unmuted one of the elements - I think it was the "Front Mic" element. Suddenly, audio started working. I then muted all the mixer elements except master and maybe PCM (if PCM was present at the time). Audio remained working. I booted back into 2.6.31. Audio still worked. I couldn't get it to stop working at that point, in order to try to reproduce the original problem. I also was not able to reproduce success on the other systems with the same hardware.
Have you tried different values for the model parameter [1]? If I am not mistaken you can use HDA-Analyzer [2] to change such values. But I never used it myself.
I tried a few values for 'model'. I have not tried HDA-Analyzer. I had hoped to avoid going in that deep.
Thanks,
