[gentoo-user] my gentoo amd64 does not have sound

hi,

my laptop is thinkpad t61. according to the output of lspci -k

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 03)
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

the driver is already loaded. and i have use alsaconf, and alsamixer
to set the configuration. /etc/init.d/alsasound is started, but my
system still does not have sound.

The T61 has audio buttons on it right? Have you tried hitting the up
volume button above the keyboard to see if the hardware mixer is muted
/ turned down?

That reminds me: on the T61 the sound starts off muted whatever settings you
have. You have to touch the unmute button to get any sound.

I have this in /etc/conf.d/local.start to save me having to do so:

echo up >> /proc/acpi/ibm/volume

HTH.

Not sure if it will apply to you, but I have an HP hdx9300. It uses
the hda-intel as well. The in kernel sound was broken after 2.6.27, and
only fixed as of 2.6.32.

You may also want to check
https://help.ubuntu.com/community/HdaIntelSoundHowto It gives a
simplified overview. The alsa site also has a lot of information. My
advice is try 2.6.32 with all the hda codecs emerged and go from there.
