No sound on Acer TravelMate 6291with Intel High Definition Audio on Fedora Core 6
I just bought a brand new Acer TravelMate 6291 and i installed Fedora Core 6 on it. Fedora recognized my onboard soundcard as Intel High Definition Audio...but when I tested it, there was no sound came out of it. anyone can help me please?

I may have a solution, at least on that worked on my Acer 3681 with Ubuntu.

Step 1: open a terminal and type:


gksu gedit /etc/modprobe.d/alsa-base
Step 2: add the following line at the end of the document


options snd-hda-intel model=auto
Step 3: Make sure that you have no sound related programs running and type:


sudo rmmod snd_hda_intel
Step 4: Type


sudo modprobe snd_hda_intel
If that doesn't work, a reboot might do the trick

Switch Fedora Core 6 to OpenSuse 10.2
Hi Janstedehouder..thank you for your quick and thoughtful reply. I decided to switch to OpenSuse 10.2 for its ability to recognise many hardwares. Unfortunately, the same problem still occur, OpenSuse recognise my Intel High Definition Audio but with no sound. So, I tried your solution with a little adaptation in OpenSuse 10.2.

I performed your step 1 with vi /etc/modprobe.d/sound and performed your step 2,3,4 verbatim and performed an init 6.

To my surprise, the problem prevails. I don't know why..but I will never give up..

so..again thank you and I hope maybe you have another solution for me? :)

Go Open Source And Bless Acer

Hi Akiglobal,
Have you tried model=acer option?

Can you post /sbin/lspci (just the part about your sound card), and also provide /proc/asound/card0/codec#0 (just the part until it says Default PCM)

No Sound on Asus Z35F - Success Story
This problem had me stumped for days and I tried 4 different distros to get the sound working, finally resolving back to Ubuntu 7.04 i386.

I followed steps 1 - 4 above with the following exceptions:
Step 2 I changed model=asus, this is what finally got the sound working.
Step 3, I received an error msg the sound card was in use so I just ignored it, no other apps were running. A restart did the trick!

thanks ntviscom, but i still can't get the sound out.

and for your request on /proc/asound/card0/codec#0, i found it empty, codec#1 isn't, oddly enough...and it has realtek in it? care you to enlight me. thanks.

Just to double check, is audio enabled in your BIOS?

ntviscom 07-14-2007 06:23 AM

This notebook contains a Realtek ALC268 sound chip which hasn't been supported
by ALSA now, but you can get the sound working if you recompile the latest ALSA sources and two patch files (

Do the following:
- download latest alsa-driver 1.0.14 from ALSA site
*- download realtek12.tar.gz from [^]
* - unpack the alsa driver
*- replace two files from the realtek12 package into alsa driver dir
*- ./configure
*- make
*- sudo make install
*- set up the soundcard with yast, add 'model=toshiba' parameter
*- reboot

Unfortunately the microphone still doesn't work.

hi mrdav1e. the sound is automatically activated..I know this because I test it with windows vista without adding supplementary drivers.
