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

[Xi Shen]

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.

what have i missed?

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.
