Description Edward T. Schlunder 2000-08-10 01:31:45 EDT

The ESS Solo1 sound card kernel module enables the microphone input on
boot. The IBM Thinkpad i1482 has integrated speakers and microphone such
that loud feedback noise erupts upon booting Red Hat pinstripe.

After booting the first time, I can login, run aumix to turn off the
microphone volume. Subsequent boot then have a short loud squirt of
feedback noise on bootup during the short time between the solo1 module
being loaded and the initscripts restoring my mixer settings, so even
fixing it manually that way isn't perfect.

maybe we can get this fixed.

Thanks, I will try that patch out next time I get a free weekend to compile the
kernel with.

Comment 4 Daryll 2001-02-23 11:44:02 EST

This problem is somewhat worse that described. Even if you turn off the
microphone at boot, it will turn itself back on again at a later time. My guess
is that the sound module gets unloaded and reloaded, and defaults to the
microphone being on.

Comment 5 Alan Cox 2002-12-14 19:58:05 EST

Closing - the fix proved to work and became mainstream. Anyone seeing hooting
esssolo should check their mixer settings as aumix remembers them from shutdown
to next boot
