Dell 1735 - ICH8 - bass control is missing


OS 11.0, x64, KDE 4.1
Dell 1735 Laptop with Intel ICH8 & Ati HD Sound Controller

The new laptop I got from Dell is having some sound problems:

Basically it works, i.e. sound card is detected, sound plays, but whenever I open the kmix application - a control slide for the bass is missing.

I’ve already tried adding

options snd-hda-intel model=dell

to modprobe.conf.local

Here’s my list of loaded snd modules:

someones-laptop:~ # lsmod |grep snd
snd_pcm_oss            72192  0
snd_mixer_oss          36096  1 snd_pcm_oss
snd_seq                87696  0
snd_seq_device         26772  1 snd_seq
snd_hda_intel         564516  2

snd_timer              45840  2 snd_seq,snd_pcm
snd_page_alloc         29328  2 snd_hda_intel,snd_pcm
snd_hwdep              28552  1 snd_hda_intel
snd                   102808  12 snd_pcm_oss,snd_mixer_oss,snd_seq,snd_seq_device,snd_hda_intel,snd_pcm,snd_timer,snd_hwdep
soundcore              26000  1 snd

during startup I get these errors from alsactl:

someones-laptop:~ # dmesg | grep error
alsactl[1452]: segfault at 0 ip 7f055c5e0d50 sp 7fff65420398 error 4<6>alsactl[1435]: segfault at 0 ip 7fef2298bd50 sp 7fff2b7cb748 error 4 in[7fef2290e000+14f000]

any hints how to resolve this issue?

Thanks. I’m not running KDE4 so I’m not sure how much I can help.

When you open your mixer and go to “settings” can you add the bass control as a parameter (check the sub-menu items there)? You probably checked that possibility already (and that may or may not be possible) but I thought it worth asking.

Note in openSUSE we typically add that setting to /etc/modprobe.d/sound file, and NOT to the modprobe.conf.local file. That should not make a difference re: your problem, BUT it will make a difference if you get recommendations from openSUSE users not in sync with what you have done.

That does not look good, … are you a ndiswrapper user for your wireless?

What version of alsa are you using? What is your hardware audio codec? (there are various ICH8 codecs). …

In order to help with sound we could use some more information … ie …with your PC connected to the internet, please start by copy and pasting the following diagnostic script into a gnome-terminal or konsole with your PC connected to the internet:

wget && su -c 'bash ./tsalsa' 

and when prompted for a password enter your root password. Please try to accurately estimate the number of jacks/plug you have when asked (for example, I have 3 i/o sound jacks on my PC), and when the script is complete it will give you a URL. Please post that URL on this thread.

Also, in addition to the above, please copy and paste the following commands one line at a time into a gnome-terminal / konsole and paste here the output of these commands:
rpm -qa | grep alsa
rpm -qa | grep pulse
rpm -q libasound2
uname -a
cat /etc/modprobe.d/sound

Nope, that doesn’t work. No bass there. Also in yast, when configuring the sound card from scratch and using it’s mixer - no bass there.

Not yet. I fear I have to use ndiswrapper soon - I’m fighting here to not have to use it :wink:

version is 1.0.17 & codec used is

It didn’t work with the script:

uploading /tmp/tsalsa.txt to

paste this url in #alsa:

but you can get the file here

I downgraded the alsa to 1.0.16 and removed the driver unstable:

rpm -qa | grep alsa

the alsactl related error during startup vanished subsequently.

Did you also get your bass control back?

no - and now I have new problem: sound seems to be totally muted. I don’t get an error when playing a mp3 or the test sound from yast - but no sound. nowhere. not even in UT :frowning:

What inspired you to roll back to 1.0.16 of alsa? Your hardware is very new, and it is quite possible it needs 1.0.18rc3 of alsa (which you had installed before).

Some speculation: To get your bass control, you may need either a custom mixer setting, or possibly find a suitable .asoundrc config file setting, … or its possible your hardware is just too new for alsa. I note a thread with a lot of Mandriva users struggling with the IDT 92HD73C1X:
Nabble - Mandriva - bugs - [Bug 42495] NEW: NO SOUND. CODEC IDT 92HD73C1X5 IS NOT SUPPORT BY SND_HDA_INTEL DRIVER

Restoring the newer 1.0.18rc3, and then write a bug on the dmesg file error may be a superior approach.

Just a further note , … I note you have a 92HD73C1X5 hardware codec on your Dell 1735. …

A dell user of a Dell Studio 17 created this web page:

If you go to the bottom of the page you will note they discovered a kernel patch to their openSUSE-11.0 was necessary to obtain the functionality they wanted from the sound device. Its possible an update to openSUSE-11.1 (which has the 2.6.27 kernel) in mid-December will sort your audio problem.

hmm I wonder why people with the same hardware get different results when trying to install Suse 11.0 on their dell laptops…

Like I said when opening the thread: sound was working, but later, due to some alsa updates, it refused to work completly. The only problem was the bass slide missing. Sound volume was never a problem.

I downloaded 11.1 beta live cd (32 bit though) a week ago - sound is working. Bass slide still missing.

On the current 11.0 x64 installation, with the latest alsa drivers during startup I don’t get any errors anymore, but sound is muted.

Having read through the page you posted the link I say it’s not a good idea to follow these instructions. Like this guy mentioned “I need to get a proper .soundrc file and alsamixer config though.” that would be more useful.
