Hi, I've already posted the below bug to the alsa-project sourceforge bug system. I'm posting this here in case it's distro specific (or you have any idea !). The bug maybe A LITTLE similar to http://bugs.gentoo.org/show_bug.cgi?id=12851 Thanks by advance for your help. Regards, Guillaume THE PROBLEM (!) Hi, I've got the same problem with an integrated i810 audio card. One thing that is VERY strange is that, even if the mixer doesn't work (and xmms also not), KDE produces sound. The config in KDE control center is "auto-detect". If I specify to use ALSA to KDE, then no more sound. Basically I don't know what kde uses to make sound ?? I'm sure there's no OSS module loaded (or included into the kernel), and so here are the problems I get : Reproducible: Always Steps to Reproduce: if i try to stop/start the alsa daemon: /usr/sbin/alsactl: get_controls:486: snd_ctl_open error: Sound protocol is not compatible if i try to launch the amixer gentoop4 root # amixer amixer: Mixer attach default error: Sound protocol is not compatible or xmms gentoop4 root # xmms ** WARNING **: snd_mixer_attach: Sound protocol is not compatible gentoop4 root # Here'are my alsa packages versions : * media-libs/alsa-lib Latest version available: 0.9.0_rc6 Latest version installed: 0.9.0_rc6 * media-libs/alsa-oss Latest version available: 0.9.0_rc1 Latest version installed: 0.9.0_rc1 * media-plugins/alsa-xmms Latest version available: 0.9.5 Latest version installed: 0.9.5 * media-sound/alsa-driver Latest version available: 0.9.0_rc6 Latest version installed: 0.9.0_rc6 * media-sound/alsa-tools Latest version available: 0.9.0_rc6 Latest version installed: 0.9.0_rc6 * media-sound/alsa-utils Latest version available: 0.9.0_rc6 Latest version installed: 0.9.0_rc6 Here's the output of lsmod : Module Size Used by Tainted: P snd-seq 43664 0 (autoclean) snd-seq-device 4104 0 (autoclean) [snd-seq] snd-pcm-oss 20088 1 (autoclean) snd-pcm-plugin 15120 0 (autoclean) [snd-pcm-oss] snd-mixer-oss 5340 1 (autoclean) [snd-pcm-oss] snd-card-intel8x0 10408 2 snd-pcm 34784 0 [snd-pcm-oss snd-pcm-plugin snd-card-intel8x0] snd-timer 10452 0 [snd-seq snd-pcm] snd-ac97-codec 29288 0 [snd-card-intel8x0] snd-mixer 25956 0 [snd-mixer-oss snd-ac97-codec] snd 33856 1 [snd-seq snd-seq-device snd-pcm-oss snd-pcm-plugin snd-mixer-oss snd-card-intel8x0 snd-pcm snd-timer snd-ac97-codec snd-mixer] rtc 6944 0 (autoclean) lirc_serial 7264 0 lm75 3424 0 i2c-i801 4592 0 (unused) i2c-proc 6384 0 [lm75] i2c-dev 3972 0 (unused) i2c-algo-bit 6568 0 (unused) i2c-core 11396 0 [lm75 i2c-i801 i2c-proc i2c-dev i2c-algo-bit] usb-storage 22000 0 (unused) sd_mod 10256 0 (unused) visor 8776 0 (unused) usbserial 16124 0 [visor] NVdriver 1067360 10 unicorn_pci 520840 0 (unused) unicorn_atm 13472 2 [unicorn_pci] and finally : gentoop4 root # cat /etc/modules.d/alsa # Alsa 0.9.X kernel modules' configuration file. # $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-driver/files/alsa-modules.conf-rc,v 1.1 2002/12/21 06:31:52 agenkin Exp $ # ALSA portion alias char-major-116 snd alias snd-card-0 snd-card-intel8x0 # alias snd-card-0 snd-intel8x0 # module options should go here # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # options snd-cmipci snd_id="first" snd_enable_midi="1" # Set this to the correct number of cards. # options snd cards_limit=1 alias /dev/mixer snd-mixer-oss alias /dev/dsp snd-pcm-oss alias /dev/midi snd-seq-oss Thanks by advance for your help, i'm ready for any testing and i'm still investigating on my side.
The problem is solved with thoose versions that i forced (i'm arch=x86 not dev): [ebuild UD] media-sound/alsa-driver-0.9.0_rc6 [0.9.0_rc8] [ebuild UD] media-libs/alsa-lib-0.9.0_rc6 [0.9.0_rc7] [ebuild R ] media-sound/alsa-tools-0.9.0_rc6 in fact, before this, snd-intel8x0 was absent ( a pb in the e-build of alsa-driver-0.9.0_rc6 i guess) and i had to load the old snd-card-intel8x0 which happened to actually be very old ! So with thoose version and snd-intel8x0 in /etc/modules.d/alsa all is working perfectly. In case somebody looks for it, i'm joining my config file. I think you may close the bug.

is this still a problem ?
No, as I wrote in the <a href="http://bugs.gentoo.org/show_bug.cgi?id=16797#c1">comment #1</a>, newer version of alsa packages solved the problem. By memory this was before the 1.4 gentoo, so for new installs, problem should never happen. Hope this helps. Guillaume.
