[gentoo-user] ALSA_CARDS Variable in-kernel drivers?
Hi! I just read about the required ALSA_CARDS variable when using in-kernel drivers in the Gentoo Newsletter. Since I am using in-kernel ALSA drivers I would like to know what changed and why this is required? Is this explained somewhere? I am using vanilla-sources (not gentoo-sources). So do I need to set ALSA_CARDS when using vanilla-sources too?

The GWN seems clear: for users using the in-kernel drivers, they should now properly set that variable I think that the other alsa packages must be aware of it. Anyway I think setting it shouldn't harm. Context from the GWN in question: In the past days there were a few changes to two ALSA packages, media-sound/alsa-firmware-1.0.14_rc2-r1 and media-sound/alsa-tools-1.0.14_rc1-r1. These two ebuilds now make use of the ALSA_CARDS variable to decide which firmwares to install and which tools to build. So it looks to me like it has nothing to do with the kernel. I can't check the ebuilds right now, but my guess is that they would explain what those two packages need the variable for, and what has changed. -- Ryan W Sims -- gentoo-user@gentoo.org mailing list
