Hello, Since Yesterday I got these errors, but with gnome-alsamixer everything is fine, and I can hear sound etc. $ amixer amixer: Mixer attach default error: Invalid argument $ alsamixer alsamixer: function snd_ctl_open failed for default: Invalid argument I patched 2.6.18 with Ingo Molnars rt patch 2.6.18-rt3. This worked flawlessy. Yesterday I recompiled that kernel without changing anything in spite of the nvidia beta driver. I had to leave make-kpkg kernel-image out, and do modules-image only, I guess :( $ dpkg -l *nvidia* |grep ^ii ii nvidia-glx 1.0.9625+2.6.18-rt3 NVIDIA binary XFree86 4.x/X.Org driver ii nvidia-glx-dev 1.0.9625+2.6.18-rt3 NVIDIA binary XFree86 4.x/X.Org driver devel ii nvidia-kernel-2.6.18-rt3 1.0.9625-0ubuntu3+1 NVIDIA binary kernel module for Linux 2.6.18 ii nvidia-kernel-common 20051028+1 NVIDIA binary kernel module common files ii nvidia-kernel-source 1.0.9625+2.6.18-rt3 NVIDIA binary kernel module source $ lsmod|egrep "(snd|sound)"|grep mixer snd_mixer_oss 20608 2 snd_pcm_oss snd 69824 14 snd_seq_oss,snd_seq,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_mpu401,snd_mpu401_uart,snd_rawmidi,snd_seq_device,snd_pcm,snd_timer $ modprobe -l|grep mixer /lib/modules/2.6.18-rt3/kernel/sound/core/oss/snd-mixer-oss.ko /lib/modules/2.6.18-rt3/kernel/drivers/media/video/tvmixer.ko $ modinfo soundcore filename: /lib/modules/2.6.18-rt3/kernel/sound/soundcore.ko [...] vermagic: 2.6.18-rt3 SMP preempt mod_unload gcc-4.0 $ uname -a Linux ubuntu 2.6.18-rt3 #1 SMP PREEMPT Sun Oct 1 21:14:11 CEST 2006 x86_64 GNU/Linux dpkg -l gnome-alsamixer alsamixergui alsa-utils ri alsa-utils 1.0.10-1ubuntu14 ii alsamixergui 0.9.0rc2-1-9 ii gnome-alsamixer 0.9.6-3
