I have an ABIT IS7 motherboard with built-in audio. Following the ALSA configuration guide (http://www.gentoo.org/doc/en/alsa-guide.xml) I was able to get it working when I first installed Gentoo about a month ago, which I tested out by playing a .wav file with /usr/bin/aplay. However, apparently something I have emerged since then (possibly newer versions of ALSA itself) have broken that functionality, so that I now only get this: > aplay /usr/kde/3.1/share/sounds/pop.wav Playing WAVE '/usr/kde/3.1/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: pcm_rate.c:512: snd_pcm_rate_init: Assertion `0' failed. Aborted by signal Aborted... Re-emerging alsa-driver has not helped.

Can you please try alsa-drivers-1.2.0c which I just added... I really doubt that will fix it, but it's worth a shot... Assuming that fails, can you trt going down to alsa-drivers-0.9.8 to see if that older version works?
Here is a summary of what didn't solve the problem, and what finally did: --------------------------------------------------------------------------- 1) Installing alsa-driver-1.0.2c: no change 2) Downgrading to alsa-driver-0.9.8: no change 3) Downgrading to alsa-driver-0.9.8 and alsa-utils-0.9.8: no change 4) Uninstalling all alsa-related packages, removing /lib/modules/2.4.23_pre8-gss-r2/ completely, rebuilding and reinstalling the kernel and kernel modules, re-emerging all alsa-related packages: SUCCESS My current (working) set of packages is: alsa-lib: 1.0.2 alsa-oss: 1.0.2 alsa-xmms: 0.9.12 alsa-driver: 1.0.2c alsa-firmware: 1.0.2 alsa-tools: 1.0.2 alsa-utils: 1.0.2 alsamixergui: 0.9.0.1.2-r3 I guess something must have been left over (perhaps under the kernel modules directory) that was interfering with newer versions of ALSA? At any rate, I am a happy camper now.
Ok, I'm closing this since the problem seems to be fixed... if you figure out a way to reproduce it, please reopen this bug.
Please re-open for the proper fix. See this comment: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg11834.html Please change the summary to: alsa-lib 1.0.2 original has pcm rate bug, new alsa-lib 1.0.2 released The original alsa-lib package had a bug in the code. If you emerge alsa-lib again you'll get a back md5sum from the original file. Re-emerging the alsa-lib package will fix any program that exhibits this, including artsd. artsd: pcm_rate.c:512: snd_pcm_rate_init: Assertion `0' failed. Please make a new alsa-lib release that just bumps the ebuild version so this hidden bug goes away AND make sure all the mirrors have the current version of alsa-lib .
