Sound Problems (Acer 5672)

Thread Starter 
Hello everyone.

I am relatively new to Linux, and have just completed an install of SuSE 10.1 (KDE) on my Acer 5672wlmi (x1600 card). I don't remember why I chose SuSE, but that's what I've got. Installation had almost no problems. I installed the ATI drivers and drivers for my Intel wireless card and both worked very well.

So here we get to my problem. The sound does work upon boot, but whenever I try to plug my headphones into the SPDIF port on the front of my Acer, and I get no sound. So I remove the headphones and now there is no sound on the external speakers either. Any help with this would be greatly appreciated.

If I cannot get it fixed I will consider kubuntu as I have seen a lot of support for ubuntu on these forums.

Thanks,

Travis

This is going to be an obvious thing, but I have to ask just in case... Your SPDIF port also doubles as a headphone port? Or is it a regular SPDIF in which case that would be why your headphones dont work Seablade

It doubles as both ports. And I know that it works because Windows XP has no problems with it.

Just making sure.

To be honest, I have never dealt with the autosensing ports like that so I am not sure I can be to much help. Especially if your sound is working when you boot, it seems like it is set up at least almost correctly.

I might look at dmesg when you plug in your headphones and see if an error message is spit out to there that might give us a clue as to where to go from there, or someone with more experience on the autosensing ports can jump in

The problem is a bug in alsa-driver. The developers have already fixed this bug. Just check out this link for more details:

https://bugtrack.alsa-project.org/al...ew.php?id=2104

(If you get the Alsa bugtrack login screen just click on guest view and it should take you to the right page)

Here's instructions on how to build the source and apply the patch;

1. Download alsa.patch from https://bugtrack.alsa-project.org/al...ew.php?id=2378
2. Download and unpack the alsa-driver 1.0.12rc3 source from ftp://ftp.alsa-project.org/pub/drive....12rc3.tar.bz2
3. Patch the source code by entering in
Code:
patch -p1 < /path/to/acer.patch
(when prompted for the file to patch enter)
/path/to/alsa-driver-1.0.12rc3/alsa-kernel/pci/hda/patch_realtek.c

4. Compile the driver:
Code:
./configure --with-cards=hda-intel
make
sudo make install

5. Edit appropriate modules and config files such as

Code:
/etc/modules:
snd-hda-intel model=ACER

/etc/modprobe.d/snd-hda-intel.modprobe
options snd-hda-intel model=ACER

/etc/modprobe.d/alsa-base
options snd-hda-intel model=ACER

These are from an Ubuntu thread so these edits apply to Ubuntu. Your modules/config files may be different..

6. Reboot

The patch will likely be added to the ALSA 1.0.13rc1 version. So depending on which version is current with your distro, you may have, or get the patch soon.

BTW, if this is the fix, then all distros would give you this same problem..

Well guys, thanks for the help. The sound is now working perfectly. Hopefully it stays that way.

I couldn't really follow the directions as jasn put them, but thanks for pointing me to the patch, which did wonders.
