Bug 172229 – media-sound/alsa-driver-1.0.14* and 2.6.20* kernel sources don't play well together for S/PDIF in and out

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Petteri Räty (RETIRED) 2007-03-25 20:18:52 UTC]

23:08 <@dsd_> Betelgeuse: file it anyway, if it isnt definitive enough i'll close it (but at least it is documented at that point)

I have both optical S/PDIF out and in that I use every once in a while and haven't been able to get both of them working since my days with a libata git kernel:

betelgeuse@pena /usr/src/libata/git $ git-describe
v2.6.19-3060-ge61d5fd

Nowadays I quite often get a crackling sound out of the digital out that goes away randomly. I think this might have something to do with CONFIG_MCORE2 because alsa wasn't able to even build before I patched it:

sys-kernel/gentoo-sources-2.6.20-r4 in kernel alsa drivers are buggy as usual

If I remember right from our IRC conversation:

gentoo-sources-2.6.19 and gentoo-sources-2.6.20 both have this bug. Did you test 2.6.21-rc5?

Which sound chip do you have?

2.6.21_rc1 had the same problem but I can test rc5.

linux-2.6.21_rc5 and still nothing from input. Talking with #alsa people to see if they can help.
