Wonder if anyone can offer setup / install advice ... I'm trying to set up the ALSA system but am getting some persistent glitches : primarily sound quality that "breaks up" or fragments when the musical content begins to grow complex or volume increases beyond a certain point. The following error messages appear at boot :
ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:464: cs46xx: failure waiting for FIFO command to complete ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:163: AC'97 read problem (ACSTS_VSTS), codec_index 1, reg = 0x0 Running Debian Woody (testing/unstable) with a custom 2.4.20 kernel on an IBM A22p, which has a Cirrus Logic CS4614/22/24/ Crystal SoundFusion audio device ; the ALSA version is 0.9.0rc6-3 ... Have googled and RTFM (all I could find, that is) and only discovered that the kernel was supposed to be compiled with sound support, but no in-kernel driver - which is how I set it up. I am using XMMS to play CD's, with its AudioCD Reader 0.14a (libcdread.so) input plugin and the ALSA 0.9 (libALSA.so) output plugin. Is it worth setting up JACK ? Have attached some (possibly) relevant config. Best wishes and thanks in advance for the attention, Chris Gianniotis
