I tried a bunch of fixup models (and even defined one myself), but none
of them made the internal microhpone work. Funny enough, the
definitions involving "DELL" work best.
Here's what I tried:
ALC269_FIXUP_ASPIRE_HEADSET_MIC, ALC255_FIXUP_ASPIRE_HEADSET_MIC [*]:
Combined headset plugged into the hack works. PLugging in a "pure" mic
doesn't. pavuctl says "Headset Microphone (unplugged)".
ALC255_FIXUP_HEADSET_MODE, ALC255_FIXUP_HEADSET_MODE_NO_HP_MIC:
No mic works, pavuctl: "Analog Input"
ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, ALC269_FIXUP_DELL1_MIC_NO_PRESENCE:
pavuctl: "Headset Microhpone" & "Microphone". Both kinds of microphone
work (after sometimes manually selecting the right thing in pavuctl),
but the "pure" mix has a 50 Hz noise on it that goes away when I unplug
all cable. Notice that this is running the laptop in a different place
and with a different mic than when I previously tried just passing an
option to the vanilla module, so I don't know whether the 50 Hz hum also
appears in the other conditions. There's no 50 Hz hum with the
"combined" headset.
There's a weird bug: When starting Audacity, playback breaks and I
have to switch (in pavuctl) to "Microphone" and then back to "Headset
Microphone" to make it work again.
[*] See attached patch. Notice that I don't know what I am doing here,
I am just pattern-matching.
I can't realistically try all the hundreds of fixups, so I tried those
that sounded most realistic and those that mention ALC255 (which seems
to be the chip I have). However, as can be seen above, ALC269-fixups
vs. ALC255-fixups doesn't seem to make any difference.
Kind regards,
Ralf
