Title:
internal mic is extreamly quiet
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Hello,
The internal mic of my Dell Vostro 1500 is extreamly quiet. It does work but
one need to shout to get anything recorded. I've been trying to use all the
STAC9025 models
STAC9205/9254
=============
ref Reference board
dell-m42 Dell (unknown)
dell-m43 Dell Precision
dell-m44 Dell Inspiron
eapd Keep EAPD on (e.g. Gateway T1616)
auto BIOS setup (default)
in /etc/modprobe.d/alsa-base.conf, but non of these changed the signal
level.
I was also playing with alsamixer and various settings including
muting left/right channel as suggested in some other page without any
effect.
The mic works good in vista.
