Even i am facing the same situation and replugging audio jack didn't help me. Also mute button of my keyboard just muted/unmuted internal speaker.
Here is output of my /dev/sndstat ######################################################### [EMAIL PROTECTED]:~$ cat /dev/sndstat Sound Driver:3.8.1a-980706 (ALSA v1.0.16 emulation code) Kernel: Linux gopala-desktop 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 Config options: 0 Installed drivers: Type 10: ALSA emulation Card config: Internal PC-Speaker at port 0x61 HDA ATI SB at 0xfe024000 irq 19 Audio devices: 0: pcsp 1: ALC861 Analog (DUPLEX) Synth devices: NOT ENABLED IN CONFIG Midi devices: NOT ENABLED IN CONFIG Timers: 7: system timer Mixers: 0: PC-Speaker 1: Realtek ALC861 ##################################################### I think since the pc-speaker is first in the list, all the sound is being played through it. I discovered a workaround for me though. I used the following command sudo alsa force-reload After this, the output of /dev/sndstat has my card as first device and also realtek mixer is first in the list.
