no sound acer aspire one

[skike]

I have installed 11.1 from DVD to the same computer (Acer Aspire one 10" netbook) which was analysed in a related post. Everything is OK, except the louder does not work. Earphone is OK, as it is written in other posts.

I tried to do that is suggested in this post, but nothing good happened.

Some idea?

When you copied and pasted your original post, the URL was corrupted. I believe this is the URL you are referring to: http://www.alsa-project.org/db/?f=38...ebadf35ed481cdand yes they are not the same. click on the quote you provided - it goes no where. Click on the quote I provided - it should work.

I note your acer aspire one is running a 32-bit openSUSE-11.1 with a 2.6.27.9-pae kernel. Your acer aspire has an ALC272 hardware audio codec.

I looked at your mixer settings from the diagnostic script, and also looked at the rpm list you provided, and I can not see anything that is obviously wrong.

You could try updating your alsa version from 1.0.17/1.0.18 to 1.0.20. You can do that by opening a terminal or konsole, and type 'su' (no quotes, enter root password when prompted) to get root permissions, and then with your acer aspire one connected to the internet, copy and paste and execute into the terminal/konsole the following commands one at a time:

zypper ar http://download.opensuse.org/repositories/multimedia:/audio/openSUSE_11.1/ multimedia

zypper install alsa-utils alsa-oss alsa-plugins alsa-plugins-pulse alsa-tools alsa-firmware

zypper rr multimedia

zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.1/ multimedia

zypper install alsa-driver-kmp-pae

zypper rr multimedia

Then restart your PC and test your sound.

The line in red makes no sense to me.

I recommend you delete /etc/modprobe.d/sound file and then after rebooting with the new alsa version, go to YaST > Hardware > Sound and set up your sound card. That will regenerate the /etc/modprobe.d/sound file.

Thanks for the suggestions. I have already update the alsa in the way you described in the answer. However it did not help. So I went back to the original version. You wrote that a different kernel is needed for the acer aspire one. Maybe I have to update kernel previously and then update alsa(?) But I do not know how to update kernel! (I am not a newby in SuSE, but I am rather an "user", sorry.

Updating to a SuSE-GmbH provided "official" kernel is relatively easy, although it is good to take a few precautions, and the complexity involved depends mostly on the hardware and drivers on one's PC. Updating a kernel may break drivers that are compiled specific to the older kernel. Those drivers typically are

• graphics card driver;
• wireless driver;
• sound driver;
• webcam driver;
• virtual box;

So for example what I do, before any kernel update, is first check that there are 'drivers' (typically packaged in rpms) for those functions/drivers that I mentioned. The most current openSUSE-11.1 kernel is the 2.6.27.21 and so before updating, I would check what those drivers are.

Now if one is using the openGL graphic driver (as opposed to a proprietary graphic driver) then typically one need not worry about a kernel update. For sound, typically the SuSE-GmbH alsa packager will package alsa rpms for the new kernel. For virtual box, one just sends a command from the konsole to rebuild the virtual box aspects that need up updated for the new kernel. But for wireless and webcam, typically one needs to go to a place like web pin Webpin and search for rpms for the new kernel. I recommend searching BEFORE updating the kernel.

Then, also before updating to a new kernel, I find it useful to make a backup copy of the /boot/grub/menu.lst file, where that file is typically modified during the installation of the rpms for the kernel update. Then after the update is done, I compare the old menu.lst file against the new and make certain they are ok.

Note if one is unhappy with the new kernel, as long as one has the installation CD/DVD, it is typically possible to roll back to the old kernel.

There are also ways to have more than one kernel installed, in a dual (or tri, or quad, or whatever) boot selection. Of course the drivers will only be tuned to one of the installed kernels and not to all. But explanation as to how that can be done is outside the scope of this post.

Now something really strange has happened (at least for me.) I updated the alsa again as you suggested. Additionally I deleted the sound file as you suggested. The voice appeared!!! I was happy, but I relised that the wlan connection is dissapear. I change to the windows partition (to write thys symptoms) but the sound became bad in windows, and the wlan connection disappear here too! Then I goes back to the original version of alsa. Nothing has happened. Then I realised that the alsa update load a new packadge (alsa-driver-kpm-pae) I deleted this packadge, and winwows works well. Then I made reparing from dvd and now linux is ok again, but no sound (again.)

I am a bit worry about the kernel update, since this simple alsa update caused a lot of strange symtoms.

One rather speculative possibility, is that the loading of the wlan is interfering with the loading of the alsa sound driver.

Try this :

• get your linux wlan working, and then
• with wlan working, test your linux audio and then
• if your linux audio is not working, type: su -c 'rcalsasound restart' and enter root password when prompted for a password, and test your sound.

The theory/speculative idea we are testing is to see if reloading the sound driver later (ie loading it long after wlan has been loaded) might help.

I have done what you recommended. The sound driver is restarted, but nothing has happened. No sound, but earphone is working.
(Now I am using the original alsa versions, not the updated one)

I do not know whether is important or not, but I use KDE3 not the newest version 4.

IMHO you have a superior chance with KDE3. KDE4 has quirks and it is more difficult wrt sound.

I am beginning to believe that I can not help. But one last attempt.

With your wireless set up to work, please reboot and test your sound. I assume only headphone will work. Then restart your sound with su -c 'rcalsasound restart'

Then test sound again (be certain to check the settings in your mixer kmix).

And then with your PC connected to the internet run the following command to post your dmesg output to the web:

dmesg > dmesg.txt && curl -F file=@dmesg.txt nopaste.com/a

and post here the URL it gives. ONLY post the URL. Maybe the dmesg will give a hint as to what is going wrong.

I have lost track. What version of alsa, and what kernel version do you have installed now?
