Question All audio/video are playing but no sound in Slackware 12.1.


Hi friends,

I've P5KPL-CM mother board with VIA VT1708B 8 -Channel High-Definition Audio CODEC.

I've installed slackware successfully in my machine after facing some problem with LILO and went with GRUB by digging in the linuxquestions.org.

Finally I got Linux working fine but when I wanted hear songs while doing other stuff I's facing problem.

Everything looks normal in KDE and Kmixer also.
It's showing only one sound card as HD audio as mentioned in motherboard details. Kmix shows only Headphone, PCM and Digital( which in default is getting value as zero). I've kept as high as 27 for these.
Kmix shows only capture and Digital in INPUT tab.

Same thing is repeated in Alsamixer.

After I searched in our forum and googled I tried to stop artsd daemon / using some other user graphical interface( XFCE and Fluxbox) but every where I'm seeing It's playing music /video with no sound in the speakers.

Please help me out of this problem.

Thanks in Advance.

Sathiya

It may be helpful if you post the output of '/sbin/lspci -vv' or just the relevant audio part of it.

Also post the output of 'lsmod | grep snd' or just 'lsmod'.

You're sure everything is unmuted in alsamixer, press 'm' to unmute channels.

I was tearing my hair out over this one when I went from 12.1 to 12.2 (I always do a clean install...Never an 'upgrade'. For me, it's just neater. I have all my "special" programs pre-packaged on a seperate dvd).

Finally, after several hours, and making sure the user was in the 'audio' group, and still not getting sound, I remembered that I never ran 'alsaconf'. I went ahead and did it, and no issues since.

I always run alsaconf even before trying to use alsamixer.

I was just letting everybody know that sometimes we all do silly things...

I even forgot to install my Nvidia driver once(Yep. Even with my post about dri...lol), and couldn't figure out why dri wasn't enabled...

After running alsaconf, Kmix and alsamixer with changing the volume levels and mute/unmute then only I posted my problem.

Even dmidecode output shows all the audio sockets for my motherboard.


After taking these logs I just thought of cheking in my motherboard CD and found some Linuxdriver directory. I found drivers for LAN and VIA-Audio. For my unfortunate time, Without going through the INSTALL script just I ran it and got an error as follows,

make[1]: Entering directory `/usr/src/linux-headers-2.6.24-smp/scripts/Makefile.build:46: *** CFLAGS was changed in
"/root/LinuxDrivers/VIA_Audio/via-linux-audiopackV1.5.1/acore/Makefile". Fix it to use EXTRA_CFLAGS. Stop.


Then I read the install script and came to know that all the modules got removed. I's trying yesterday whole night till 3am to make it compiled But It's in vain.

When I rebooted the machine Kmix gave an error like unable locate /dev/dsp. Alsaconf also showed no drivers are there to be used (neither normal drivers nor legacy drivers). Then I got really frustrated and ran once again the lsmod to find any changes. lsmod showed only one line for sound as like as follows,

soundcore 9824 0

lspci output was not changed.


Please advise me what I should do now my friends. Now I'm really in fix. Since I'm not having internet in my machine it's taking time to reply you. Here My frieds are telling to reinstall the slackware freshly. I don't know what to do.

Please help me to get rid of this problem

Everything looked fine before the modules disappeared like you said.

I would try to re-install the modules. If you're running the smp kernel check 'uname -r' then 'installpkg' the 'kernel-modules-smp-2.6.24.5_smp-i686-2.tgz' package, if the regular kernel then use the 'kernel-modules-2.6.24.5-i486-2.tgz' package. If you can login to the box then just get these off the Slackware DVD. If you cannot boot to a command line then put in the Slackware DVD, boot up, then 'chroot' to your root partition (mount it if necessary) and 'installpkg' the packages from the DVD. This is so that the packages are installed to your system.

A possible solution, mostly for asus laptop, but it might work here too:

If not, then try looking up more options for the driver.
