Description P. Beltrani 2003-08-08 22:53:30 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624

Description of problem:
The C-Media CM8x38 chips have a microphone gain bit that activates a microphone
preamp feature.  (See the CMI8338 Specs regarding the MICGAINZ bit.)

This bit is not set by the current driver.  As a result, many microphones can
not be used successfully with this driver/chipset combination.

Attached is a patch to the module that allows this bit to be set via the module
parameter "micgain".

Version-Release number of selected component (if applicable):

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
