alsa-info output for 5.4 kernel (-164.el5)
Created attachment 361015 [details]
alsa-info output for previous kernel (-128.7.1.el5)
I neglected to mention in the initial problem description that the customer has raised/un-muted all available sliders in kmix/channels in alsamixer under the new kernel. So it would appear that the channel which controls output volume on this ALC262 implementation has been hidden/removed in 5.4. Please, could you try add 'model=tyan' for as parameter for the snd-hda-intel module? customer reports adding 'model=tyan' doesn't help --- I modified /etc/modprobe.conf to add 'model=tyan' as an option for the snd-hda-intel module, and then reloaded the driver: % modprobe -r snd_hda_intel % modprobe snd_hda_intel The system log confirms that the driver was successfully reloaded. The addition of "model=tyan' does not seem to have any effect at all. --- Thank you for feedback. Please, try another models: model=auto and model=basic . The latest ALSA HDA driver for RHEL 5.5 is available here: http://people.redhat.com/~jkysela/RHEL5/ Please, report back test results for updated kernel. The problem in this bug might be resolved in this update. customer reports that the test kernel from comment 11 works properly w/ defaults (no extra module options necessary). he also states that for his hardware the "model=basic" option provides the best results. > With the test kernel it is no longer necessary to specify an option for the > snd-hda-intel module. The default now seems to be "model=auto", as it should be. > > The most full-featured option for my hardware appears to be "model=basic". > Sound works with that option, but it appears to me that the "Headphone" > playback volume (which is the second control and controls the front speaker > volume) is where the "PCM" playback volume control should be. That is, the > "PCM" control should be second, and maybe the "Headphone" control should be > third (or somewhere else)? Marking as duplicate of parent bug#525390 . Please, re-open this bug in case of any related issues with future RHEL 5.5 kernels. *** This bug has been marked as a duplicate of bug 525390 *** An advisory has been issued which should help the problem described in this bug report.
