Yes, the parser has learned to recognize more controls, among other
changes. See "git log v3.1.8..v3.2.1 --grep=[Rr]ealtek" for details.
The symptoms are similar to
(silent output on ASUS A6Rp). The regression is probably due to
v3.2-rc1~38^2~69 (ALSA: hda - Remove all ALC861 and ALC861-VD quirks,
2011-08-23). Unfortunately, since you have an F3JC and F3JA
respectively, the fix applied upstream (3b25eb690e8c, ALSA: hda - Fix
silent output on ASUS A6Rp) will need tweaking before it can help.
Please contact firstname.lastname@example.org, cc-ing Takashi Iwai
<email@example.com> and either me or this bug log so we can track it.
Be sure to include:
- steps to reproduce
- what versions you've tried, and in particular what the newest
working and oldest nonworking versions you've tried are
- links to alsa-info output and other logs
- a pointer to this bug log for the full story
If you have time for it, please also follow the instructions from
https://bugzilla.kernel.org/show_bug.cgi?id=42588#c18 to get some
pin routing information (instructions for building a patched kernel on
Debian are at ).
Thanks much, and good luck,
