ALSA, Audigy2 Value and 2.6.12.2 Kernel

Slack1_more · 07-13-2005, 02:30 AM

Hi Slackers!
I just upgraded my kernel successfully from the Slackware 10.1 standard 2.4.29 release to 2.6.12.2.
Had some problems with blank screens and nvidia module which I overcame, but I am stumped about how to get over my problems with ALSA.
I have a Creative Audigy 2 Value card, and although the 2.4.29 kernel/ALSA combination from the Slackware 10.1 release recognised the card, apparently the new kernel does not.
I noticed that when booting into Slackware 10.1 it seems to recognise that Audigy 2 Value uses a Sigmatel STAC 9750/51 chip.
When I boot into my 2.6.12.2 kernel Slackware, it does not recognise any soundcard at all (/proc/asound/cards contains the words "--- no soundcards ---" ).
Has anyone resolved this problem?

Any help gratefully appreciated.

Make sure you've ticked the appropriate box in the kernel config for "Sigmatel STAC 9750/51" (hammering the ALSA site shows me that the Audigy 2 ZS Value needs the emu10k1 module) and run, as root:

Code:

piete,
thanks for the message, but I can't find that chip mentioned anywhere in the Kernel config.
???

I would say you're probably not looking hard enough

Your .config file needs to include something like this:

Code:

#
# PCI devices
#
CONFIG_SND_AC97_CODEC=m
# CONFIG_SND_ALI5451 is not set
# CONFIG_SND_ATIIXP is not set
# CONFIG_SND_ATIIXP_MODEM is not set
# CONFIG_SND_AU8810 is not set
# CONFIG_SND_AU8820 is not set
# CONFIG_SND_AU8830 is not set
# CONFIG_SND_AZT3328 is not set
# CONFIG_SND_BT87X is not set
# CONFIG_SND_CS46XX is not set
# CONFIG_SND_CS4281 is not set
CONFIG_SND_EMU10K1=m
# CONFIG_SND_EMU10K1X is not set

Note the CONFIG_SND_EMU10K1=m

In something like xconfig or menuconfig, it probably won't be sold as emu10k1, but rather, "SB Audigy, SB Audigy 2" or similar.

Good luck on that kernel rebuild.

Thanks piete,
seems to work now.
I can tell you one thing though, that if you compile Kernel 2.6.12.2 with all the PCI sound cards enabled you're gonna get into trouble.
At least I think that's what happened to me...

Another funny is that when I list the info from /proc/asound/cards when running the two kernels, 2.4.29 and 2.6.12.2,
I get 2 different outputs!
2.6.12.2 calls my Audigy 2 Value card an SB0400! I suppose it doesn't matter as long as it works.

Thanks again
