ALSA - sometimes only one speaker working

Hello out there,

I am a happy user of Slackware 13, but there is an annoying problem with ALSA (or anything else??) on my system.

Sometimes (rather often) only one speaker of my system plays music.

I use plain Slackware 13, without /etc/asound.conf and ~/.asoundrc

-- ALSA restart /etc/rc.d/rc.alsa doesn`t help
-- muting/unmuting the mixer doesn`t help
-- Rebooting the PC helps - most of the times

Does anybody has the same problem or a solution ??

Thanks for all help!!


1. )My Card is

bash-3.1$ cat /proc/asound/cards
0 [CA0106 ]: CA0106 - CA0106
Live! 7.1 24bit [SB0410] at 0x9c00 irq 22

2.) All modules are properly loaded

bash-3.1$ lsmod |grep snd

snd_seq_oss 29792 0

Most likely to be a hardware fault as software faults generally lead to no sound at all.

Please check your cables and connectors (try others, jiggle / reconnect the connectors while music is playing out of the one speaker).
