Dup of bug 249388 and bug 252373, close out as a dup when final patch is submitted.

I see that patch is applied to 2.6.18-43.el5, however still does not produce any
sound. Comment from fedora forum is you require.

The line in /etc/modprobe.conf that current looks like
options snd-hda-intel index=0
needs to be changed so that it looks like...
options snd-hda-intel index=0 model=thinkpad

We have tested this on both a t61 & t61p and this works.

Is there any chance a workaround can be created so this is no longer necessary.

Also affects F7 kernels through kernel-2.6.22.4-65.fc7.

And the workaround in Comment #2 does not help on F7.

I should of mentioned, you open "volume control" and enable the speaker.

I open the volume control and only see the Playback tab and Master control.  It
is not muted and volume is up full.

scsconfig.log attached.

Matthew this ticket is/was opened for RHEL5 U1 not FC7.
