RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jiri Koten 2016-03-22 10:15:00 UTC

alsa-info

Description of problem:
Multi-channel audio is broken on Creative Labs CA0106 Soundblaster [1102:0007]


Version-Release number of selected component (if applicable):
alsa-utils-1.1.0-3.el6
alsa-lib-1.1.0-4.el6
kernel-2.6.32-629.el6

How reproducible:
100%

Steps to Reproduce:
1. speaker-test -Dsurround51:CA0106 -twav -c6
2.
3.

Actual results:
Sound is audible only from Front Left, Rear Left, Front Center channels, others are silent.

Expected results:
Sound is audible from all channels.

Additional info:
It's a regression, I have tested the setup with alsa-utils-1.0.22-9.el6_6 and it works correctly. Also hw specific, other cards like Creative Labs SB0400 Audigy2 Value [1102:0008] are working correctly with the new package.
Comment 2 Jaroslav Kysela 2016-03-22 12:18:45 UTC 
The mixer setting is wrong:

  Front Right: Playback 0 [0%] [-99999.99dB]

Does 'alsaunmute' command help ? (or any mixer app)
Comment 3 Jiri Koten 2016-03-22 13:11:50 UTC 
alsaunmute does nothing. I have to run: 
$ amixer -c0 sset 'Analog Front',0 81%,81% unmute

Then it's working ok.
Comment 4 Jaroslav Kysela 2016-03-22 13:18:39 UTC 
Could you add '-d' argument to alsaunmute (for alsactl) and provide the debug output?
Comment 5 Jiri Koten 2016-03-22 14:05:24 UTC 
$ alsactl -d monitor #0
card 0, #35 (2,0,0,Master Playback Switch,0) VALUE
card 0, #30 (2,0,0,Analog Front Playback Switch,0) VALUE
card 0, #31 (2,0,0,Analog Rear Playback Switch,0) VALUE
card 0, #32 (2,0,0,Analog Center/LFE Playback Switch,0) VALUE
card 0, #33 (2,0,0,Analog Side Playback Switch,0) VALUE
Comment 6 Jaroslav Kysela 2016-03-22 14:30:06 UTC 
I meant - use alsactl command like in alsaunmute script (all arguments), but add '-d'.

Comment 8 Jaroslav Kysela 2016-03-22 15:42:30 UTC 
OK, are you sure that it works with alsa-utils-1.0.22-9 ? I think that this bug must be there, too.

There must be replaced all strings {value} as {values} in file /lib/alsa/init/ca0106 to set all channels.

There is no ca0106 file in alsa-utils-1.0.22-9.

I have a fix, but I need (rhel-6.8.0 == + and blocker == +) for push to the git repository.
