[Intel Corporation 82801H (ICH8 Family)] Low Volume, No int mic, Bad ext mic quality

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello.

I have a Lenovo ThinkPad R61i

my lspci gives
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio 
Controller (rev 03)

my codec is
CX20549
which i searched and found to be the same as CX5045

I had Ubuntu installed, and never managed to listen sound to high volume 
and make the internal mic to work.
Now i have Debian Lenny. The first (experimental) installation of Lenny 
was promising. After the installation, with no other configurations the 
sound volume was great. But the next day when i installed Debian Lenny 
for the final time, the problems returned.

1) The sound volume is too low (the same as in Ubuntu installation)
2) Internal mic doesn't work
3) External mic works with unacceptably bad quality

I tried this <https://help.ubuntu.com/community/HdaIntelSoundHowto> 
guide. I found that I tried with any of the following in the 
/etc/modprobe.d/alsa-base

# options snd-hda-intel model=laptop-hpmicsense
# options snd-hda-intel model=laptop-hpsense
# options snd-hda-intel model=laptop-micsense
# options snd-hda-intel model=benq

The options are from ALSA-Configuration.txt

In one month I tried everything.

Can anybody help me? Is finally my card supported, or is gonna be 
supported some day? Shall i keep trying?

Thank you in advance.
