Hi
I was discussing yesterday with Danny on his blok http://dkukawka.blogspot.com/2006/11/kpowersave-config-tutorial.html about how to restore sound on my old laptop. He told me that I should drop you a note as my problem in reality should be handled by the kernel.
Short story is that I have a old Dell X200 with a Intel sound controller. lspci says: 00:1f.5 Multimedia audio controller: Intel Corporation 82801CA/CAM AC'97 Audio Controller (rev 02)
After a suspend cycle sound is muted on all channels until the corresponding sliders hav been moved.
For my purpose I saved a zero file (mixer setting all zero) and saved this as /etc/asound.zero. Then I made a /etc/pm/hooks/63sound script in pm-utils
#!/bin/bash case $1 in hibernate|suspend) /usr/sbin/alsactl store /usr/sbin/alsactl -f /etc/asound.zero restore ;; thaw|resume) /usr/sbin/alsactl restore ;; esac
This hack solves the problem on openSUSE 10.2. Feel free to ignore my letter as I guess most X200 is dead and gone by now - and my english is bad to :-) -- Regards Klaus - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
