You can grab the latest code immediately after commit to GIT repository (but generation of new package takes awhile as mentioned on page when it's not built on server already). The package generation is triggered from the web server by users requesting latest package immediately.

As a temporary workaround, you can change alsa-driver/kconfig-vers. This is a list of the least kernel version for some drivers, and mts64 is there, too. Change the version to 2.6.26 or such, so that it won't be built for your kernel.

[alsa-devel] Sound Blaster Audigy (snd_ca0106 Creative Labs|SB Audigy LS): How to use the mixer?
by Colin Guthrie 25 Aug '08

25 Aug '08

Hi, Just trying to help a user with a problem and it seems to be down to the fact that his SB Audigy LS does not have a "Master" or "PCM" mixer control. I asked Lennart about this and he told that Takashi said he wanted to make sure that all devices have at least a Master vol control. This one doesn't! Please let me know what you need in order to fix this. This is with 1.0.17... I can't see anything in the changelog that would suggest this is fixed in the 1.0.18rc1. Please let me know if you need e.g. PCI ids etc. as I can ask the user to provide these.

Hi all, finally, I made possible to download a very fresh ALSA code in tarballs from our repository - http://www.alsa-project.org/snapshot/ . Users can get the recent code immediately now. There is no reason to wait a day or so after commit to the GIT repository now. Jaroslav ----- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc.

[alsa-devel] ac97_channel_mode_info() needs a "0ch" added.

When attempting to leverage existing ALSA AC97 infrastructure, i realized that the existing infrastructure does not account for the 'prosumer-y' concept of repurposing ALL of the jacks as input, including the speaker. The vt1618 can use any of it's jacks as mic in or line in. if all of them are set to be inputs, then ac97_channel_mode_info() needs to return "Och" because there would be no output channels. that would imply that ac97->channel_mode would equal 0, yes? tnx for any input you can provide.
