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 Bradley Scalio 2010-05-23 15:20:37 UTC 
Description of problem:

Both the quick-keys (media keys) as well as the mixer, have a mapping issue.
The master volume control actually controls the channel, i.e. reducing the volume actually is a slider of LEFT-RIGHT speaker output.  So, for example, when the master volume is at 100% or <===========> (ASCII image of slider) both speakers are used at 100% volume.  When you reduce it to say 50% <=====     > then only the left speaker is used at 100% and the right speaker is turned off.

Launching the mixer and using the PCM control actually controls the master volume.

How reproducible:
100% reproducible

Steps to Reproduce:
1. Install RHEL6bets
2. Change volume either via media keys or master control

  
Actual results:
Speaker channel changes

Expected results:
Master volume changes

FYI the link in ADDITIONAL INFO is the alsa-info upload
Will also upload an sosreport

I realize this is a config issue - however Fedora12 and RHEL5 did not have this problem on this laptop "out-of-the-box"
Comment 4 Jaroslav Kysela 2010-05-24 07:15:57 UTC 
Could you test 'alsamixer -c0' command? (The question is if you use Pulse Audio mixer or if you use directly the hardware mixer). Also, attach output for 'alsa-info.sh --no-upload' for a non-working setup (unbalanced channels).
Comment 5 Bradley Scalio 2010-05-24 23:02:14 UTC 
Yes, alsamixer -c0 when changing the master volume only changes the channel, not the volume

The alsa-info is also in the link provided in the "additional info" section of the original bug report but also included inline below

Thanks

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 7 RHEL Program Management 2010-07-15 14:45:40 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

I believe that this issue was fixed in recent RHEL6 kernels / ALSA utilities. Please, open a new bug otherwise.
