Acer Aspire 1642ZNWLMi audio problems


Hello.

I'm having trouble enabling audio on my Acer Aspire 1642Z laptop. Ubuntu detects my sound card, but I can't play any sounds - anywhere. I've tried with the built-in speakers and the speakerphone connection on the front of the laptop, but none of them work.

The sound card is an Intel HDA ALC833.

Here's my lspci output for the soundcard:
Code:
0000:00:1b.0 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)
Here's lsmod | grep snd output:
Code:
snd_hda_intel          18964  2
snd_hda_codec         142640  1 snd_hda_intel
snd_pcm_oss            53664  0
snd_mixer_oss          18688  2 snd_pcm_oss
snd_pcm                89864  3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer              25220  1 snd_pcm
snd                    55268  8 snd_hda_intel,snd_hda_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore              10208  2 snd
snd_page_alloc         10632  2 snd_hda_intel,snd_pcm
I have two devices in my volume control panel:
1 - OSS - Realtek ALC883
2 - Alsa - HDA Intel

I've went through all of the options for both of them, and I've unmuted and turned the volume up on all of the options. Nothing worked. I've tried compiling the drivers from the Realtek website, but it made things worse - Ubuntu didn't detect my soundcard at all after restart, so I reinstalled the OS.

Any solutions for this one?

EDIT: I'm using Ubuntu 6.06.

Thank you in advance,
Nikola

open a terminal and use alsamixer to adjust the sound settings...the audio control panel works ontop of this. Don't forget to do "alsactl save" after you make your changes.

Tried that, still nothing...

EDIT: I forgot to mention another (probably useful) piece of information... When I boot up the computer, just before I get the Ubuntu boot screen (just after GRUB finishes its work), I get the following messages:
Code:

options snd-hda-intel model=laptop

Hey, myates1980!

Unfortunately, none of that worked... When I boot the laptop with the acpi=off option, my network card and my sound card don't work at all (they don't get recognized by Ubuntu).

Unfortunately, it seems that this is a bug in ALSA. It looks like some people are working on it, so we can probably expect a solution in the nearer future. In the meantime, if anyone finds a way to make sound work on this laptop, I'd be more than thankful if he'd post the solution in here.

Thanks for your help guys!

Bugger! I just bought one of these laptops and I have the same problem. I suppose I will have to wait for the bug fix too.

There is actually a patch to solve this problem. I haven't managed to do it yet as I'm on ubuntu and can't figure how to uninstall the old version of ALSA without it messing everything else up. Anyway, I explain that in my post later in the thread this link takes you to.

Clicky!

Oh crap... I was just reading this thread thinking that someone might have solved it but then found that I made the last post on it
It's been 3 months now and I'm so sick of it.

This document claims that it's supported...
http://hg-mirror.alsa-project.org/al...t;style=gitweb
using the options=acer
I get the following error(s):
ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 209
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
hda_codec: num_steps = 0 for NID=0x9
hda_codec: num_steps = 0 for NID=0x9
hda_codec: num_steps = 0 for NID=0x9

etc ...

Solved

I managed to solve the problem using Slackware. The reason I chose that distro is because it doesn't do auto updates that would break all my hard work or dependency checking that could potentially do the same.
What I had to do was compile my own alsa (driver, lib, utils, oss) version 1.0.13. Remove all sound-based modules from /lib/modules/linux-2.17.13/sound/ and manually put in there the ones that are needed:

snd
soundcore
snd_page_alloc
snd_pcm
snd_timer
snd_hda_codec
snd_hda_intel

I then had to check that they'd get loaded in the correct order using depmod. You can find the correct order by attempting to modprobe each one and if it fails then check dmesg for what it needs.
After loading all of the modules needed it works fine! (about time too)

Peoblems solved with kernel update

Hello, the problem is easy to solve on every linux by update the kernel. I was able to solve this audio (bug) on Centos 5 by yum update kernel. The last kernels know about the chipset and work fine with audio and lan controler.
