Comment (by ttcoder):
@korli: that patch brings line-in/mic-in to 100% perfection! Though for
some reason there still needs to be verb-zero'ing as well (BTW I've found
out only one zero is needed, see below)... I've tested with/without verb
zeroing and with/without the above patch, here's the results of the
interesting combinations:
- withOUT the above diff and with zeroed verb: playback is perfect, and
microphone-in works but strangely, I have to unmute it in ''both'' the
Input pane and Output pane of the Media preflet, otherwise SoundRecorder
receives nothing. That's odd because SoundRecorder should only be affected
by "Input" settings, and that's annoying because you hear youself speak in
the mike as you record :-].. So verb zeroing alone was not enough.
- with the above diff but withOUT zeroed verb: playback is muted, but
input works somewhat now (IIRC one has to shout loudly into the mike). So
the above patch alone is not enough.
- with the above diff ''and'' with zeroed verb: '''playback''' is perfect
(even more loud/clear than when the HDA mixer is bypassed), and
'''input''' as well, meaning ticket #8333 is thoroughly fixed for me as
well: sound is loud and clear, and I just have to unmute Mic-in in the
"Input" pane of media prefs, I do not have to unmute it in the Output
pane. Perfection everywhere.
I've narrowed down the verb zero'ing though, I've realized it's sufficient
to zero out only the first, at index j=0. I'll do some cold-boot testing
in case behavior differs from a media_server warm restart but here I doubt
it has an impact:
'''if(j==0)
verb[j]=0;'''
Resulting in this syslog'ging:
{{{
KERN: hda: set_mix: 23 mixer: 3
KERN: hda: set_mix: 23 mixer muting 0 (0)
KERN: hda: set_mix: 23 mixer muting 1 (1737180)
KERN: hda: set_mix: 23 mixer muting 2 (1737280)
KERN: hda: set_mix: 23 mixer unmuting 3 (1737300)
KERN: hda: set_mix: 23 mixer muting 4 (1737480)
KERN: hda: Setting mixer 3 failed on widget 23!
}}}
Note the "failed on widget..." last line; it appeared today or maybe
yesterday; I've only noticed it now. Does not seem to impact things
anyway, apart from the need to tick/untick some checkboxes sometimes (they
seem to vary from session to session) everything is perfect.
So I guess now the question is, why does "set_mix: 23 mixer muting 0" mess
up the output (and quiets down the input IIRC) ?
