problem with SB audigy 4 - mic not record [solved]

[netjiro]

Hi,

Recently did a large upgrade, now I cannot get the mic to work right.
Using alsamixer I can get regular pcm playback and mic loopback to work right.
I can also get recording from pcm to work right but not recording from mic, just loopback.

card Audigy 4 [SB0610]
alsa module from kernel 2.6.18 emu10k1
alsa tool chain 1.0.14

mixer settings: (from amixer)

I have found a fix for this problem.

The alsa folks have a bug on this issue:0002562
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2562

The bug includes a fixed emumixer.c file.

1) Replace the emumixer.c in alsa-driver-1.0.13.tar.bz2

2) redo the digest for the alsa-driver-1.0.13.ebuild:
"ebuild alsa-driver-1.0.13.ebuild digest"

3) then emerge -1 "=media-sound/alsa-driver-1.0.13"

4) restart all alsa or reboot

This fixes the problem for me, I can now both record and playback the mic on my SB audigy 4 card.

I have opened a gentoo bug on this: 161119

Hello,

Can someone elaborate a little on point 1? How exactly does one replace the emumixer.c in alsa-driver.tar.bz2?

Thanks!

You unpack the original tar package that you can find in your distfiles directory after you have downloaded it with emerge --fetchonly.

Then you switch the old emumixer.c with for the new one.

then you repack the package with tar -cjpf packagename.tar.bz2 unpackeddir

then move the repackaged into the distfiles directory and replace the old one.

then you have to continue at step 2 above to rebuild the digest and so on.
