Description David Gardner 2001-04-28 19:00:18 UTC
This problem didn't occur under redhat 7.0 on the same computer.  I
performed a clean 7.1 install (formatted dives). sndconfig correctly
identifies the sound card, but the sounds have alot of pops and static.
Everytime I load gnome there is a loud pop over the speakers. Real player
has the most trouble in realy player I have three options : 1) use native
sound driver, 2) use ESD, or 3) use OSS. If I choose either 1 or 3 I hear a
bunch of noise like the sound is being played at the wrong frequency.
option 2 works some times, often at a low volume and sometimes I can only
hear the bass but no highs. I'm not sure what information you will need so
I will try to include as much as may be relevent. This isn't a mission
critical problem, just anoying.

So far I have tried:
Enableing/disabeling soundblaster emulation in the system bios
adding "options sb support=1" to the modules.conf file
Telling gnome not to start up sound server

Here is my modules.conf:
alias eth0 tulip 
alias parport_lowlevel parport_pc 
alias usb-controller usb-uhci 
alias sound-slot-0 via82cxxx_audio
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null
2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null
2>&1 || :

Here is my old redhat 7.0 modules.conf:
alias parport_lowlevel parport_pc
alias sound-slot-0 via82cxxx
options sb support=1
alias eth0 tulip

esd.conf [unchanged from rh7.0]
spawn_options=-terminate -nobeeps -as 2

Also I noticed that if I play an audio cd it sounds fine if I tell gnome not to
start up the sound server, but distorted otherwise.

Assigning to kernel; sounds like a driver issue.
