Hi all,
Sound is not working on my notebook hp dv7-1217ef using Alsa. I see that
this is a common problem with Intel sound harware but none of the solutions
I found on the web worked for me.
I used alsa-info.sh so that all questions regarding my software and hardware
configuration will be found here :
http://www.alsa-project.org/db/?f=48c0e20b4448fe82ccf2b395fd39a34dc33abc7e
There is one Intel card :
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio
Controller (rev 03)
and two codecs :
IDT 92HD71B7X
Nvidia MCP78 HDMI
I want to unmute de IDT 92 codec (for speakers) but the problem is that
alsamixer uses by default the wrong codec (HDMI). I followed this FAQ :
http://alsa.opensrc.org/index.php?title=FAQ026
and changed the default Slack config asound.conf to :
pcm.!default {
type hw
card 0
device 2
}
ctl.!default {
type hw
card 0
device 2
}
in order to use device 2 instead of device 0 (the default), the respectives
addresses of the codecs. But alsamixer gives this error :
alsamixer: function snd_ctl_open failed for default: Invalid argument
In order to compare behaviours, I booted a Fedora 11 live CD. And it worked
with the same alsa-drivers version (1.0.18a) as Slackware, this is why I
suspect a configuration problem. It was not possible to use the Fedora
config files to Slack because of missing plugins (plug) : packages are not
build in the same manner in the two systems.
Have you got an idea ?
Thanks,
Franck |
