Comment # 2 on bug 915858 from Graham Freeman

I installed hda-verb and tried your suggestions. The commands

 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x10
 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x10
 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x10

made sound work. This is a miracle. I have used Fedora for many years and
reported the problem to them 14 months ago when I bought this new machine. It
has been unusable for that whole period. I installed OpenSUSE last week and
sound is now working. Thank-you so much.

So should I install those commands in a start-up script somewhere, like
/etc/profile?
