Title:
[Realtek ALC271X] Recording problem
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Ubuntu 10.10 on Acer Aspire 5553
No ALC271X in alsa driver config
Recently got an Acer Aspire 5553 with Ubuntu 10.10 installed which I
am very pleased with.
The internal microphone is very noisy.
alsamixer reports it to be Realtek ALC271X.
The module loaded is snd_hda_intel
In /etc/modprobe.d/alsa-base.conf
I now have
options snd-hda-intel index=-2 model=auto
I have also tried model=acer and acer-aspire from HD-Audio-Models.txt
I have the alsa-info.sh script output here
http://www.alsa-project.org/db/?f=9f294bda9abb5aa2855ffc4d65c4c37c62121db8
Any ideas?
