Bug 161119 – alsa-driver 1.0.13 and 1.0.14_rc1 : audigy 4 mic error

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jimmy Rosen 2007-01-09 13:03:32 UTC]

The alsa-driver 1.0.13 and 1.0.14_rc1 packages has an error in the emumixer.c

This affects the possibility to record from mic on a SB audigy 4 card.
The upstream alsa has a bug on this: 0002562
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2562

I have verified that the suggested fix (just two lines of code in the emumixer.c file) corrects the problem for the alsa-driver-1.0.13 package, but I have not verified for the 1.0.14_rc1 package.

With this fix it is possible to both record and playback from mic.

Should it be fixed on our end with a tiny patch, or wait for upstream?

The emumixer.c file that fixes the problem

The diff between this file and the one in the alsa-driver-1.0.13.tar.bz2 is just two lines (that specify the mixer items, I believe).

I usually try not to patch ALSA a part from some relatively big problems, I'll see to this anyway when I'll do a new bump, if upstream don't merge it.

This should be fixed in rc2, please reopen if it's not.
