Fedora 9 - Acer Aspire 5920 - Audio not working

[unix.95054]

Hi,

I installed Fedora 9 on my Acer Aspire 5920 laptop. I am able to see system tray's sound controller, can increase/decrease/mute sound but the audio is not coming from the laptop. Not sure what/where to check.

Can anyone help me to configure audio for this laptop?

Thanks,
Fedora Newbie

I have a page on sound problems in Fedora 8--not 9. However, something might be of help. One thing with the Acers is that I've often had to add the

options snd-hda-intel model=acer
to a file I would create in /etc/modprobe.d called alsa-base.
I would try that first and see if it solves the problem. (Might require a reboot.)
The page is at http://home.nyc.rr.com/computertaijutsu/rhsound.html

I repeat it was for problems in F8, so I don't know if it will help. I have found with F9 since rawhide that I had to do the console-perms thing I mention as well as have that model=acer line on my machine, a 4720z low end laptop.

Try "cat /proc/asound/cards", "cat /proc/asound/card0/codec#0 | grep Codec". You should post your "lspci -vvv" lines about your soundcard.

As per scottro's suggestion, I created following file, but could not get the audio working.....

[root@fedora-lp modprobe.d]# cat /etc/modprobe.d/alsa-base
options snd-hda-intel model=acer


I am still looking for a solution......please help guys...

[LukSoft]

Hmm, we have the same problem, but different sound chipsets.

You are using an Acer Aspire 5920?

Hi,

Hi,

I have also an Aspire 5920, but with no sound problems. Have you checked the mixer settings (Volume Control). The internal speaker is called "Surround". The so-called "Front" controls the front socket, where you can plug-in a headphone. After that you may also change the master channel to control the volume.

[Evel2k]

THX now it works

[LukSoft]

I was able to solve my problem (no headphone output) by setting the power-on sound on in bios. Now it all works perfect.

how to change the sound in bios........?

I'm on hollidays now, so I don't have a notebook with myself. I don't know about acer, but I think I had it under boot settings.
