I have a PinkFaun I2S card. This one is using C-media CMI8888 and the
only output is I2S. What is strange is that this card is working fine
only on AMD processors (or Intel Atom) but not , for example, on Intel
i7-6700. In this last case there is a very high, noisy and distorted
sound at 192kHz. At lower sampling rates, for example 44.1, the sound is
better, but there are periodic noises.
I have disabled embedded audio in BIOS, have checked with hda-analyzer,
I have confronted the loaded modules with a working system (the modules
are the same), I have increased the buffer, I have checked with
standard, realtime and ck kernel, tried to disable c-media specific
driver and a lot of other things, without results. My system is
archlinux updated to the very last kernel and Alsa version.
What is more strange is that, if I boot from wtfplay minimal
distribution, the card is working!
I hope some people can give me some suggestions, because I have tried
everything!
