volfro Posted October 12, 2004 Report Share Posted October 12, 2004 H'lo again, I upgraded (well, formatted and installed) to 10.1 Community, which ended up fixing my keyboard/mouse issues. However, sound still skips severely, no matter the driver I try. It's onboard sound on a VIA motherboard; the default kernel driver is via_82xx or something. When I used Knoppix, the sound worked. It used the same default driver, but the kernel is 2.4.xx, while MDK10 uses 2.6. The sound in Knoppix was kinda crappy, but that's better than no sound at all; is there a way to downgrade the sound drivers in the kernel, or add older sound drivers, from that distro of Knoppix, to my drivers? I don't want to recompile the entire kernel... Thanks all. volfro Quote Link to comment Share on other sites More sharing options...
arthur Posted October 12, 2004 Report Share Posted October 12, 2004 i got the same VIA card...the ALSA driver is snd_via82xx and it's absolute crap in sound quality. you should change to the older OSS driver via82cxxx_audio, which sounds much better. Putting 'via_82cxxx_audio' in /etc/modprobe.preload will be enough to be able to use the driver. You *might* have to edit the module files to stop the ALSA module from booting...just try the above suggestion first. At last resort, compiling the kernel with the OSS module is guaranteed to work. It's not that hard... :) Quote Link to comment Share on other sites More sharing options...
volfro Posted October 12, 2004 Author Report Share Posted October 12, 2004 Okay, stupid question: I don't have permissions to edit that file. How do I edit it? I logged in as the SU, but how do I launch it as the SU? I know I've done that before, I just can't remember how... Thanks! Quote Link to comment Share on other sites More sharing options...
volfro Posted October 13, 2004 Author Report Share Posted October 13, 2004 Okay. Figured it out. But it's still no go. My sound skips terribly; the startup sound itself takes more than a minute to complete. What other module things need editing? Or is that a solution? I've been grappling with this for some time now...I want music in Linux!! thanks again Quote Link to comment Share on other sites More sharing options...
devries Posted October 13, 2004 Report Share Posted October 13, 2004 I think its best when you configure the soundcard with the MCC. If you have setup everything correctly, try different mixer settings (open kmix or alsamixergui). Stop/start arts, experiment with different xmmx plugins, with different players etc etc. Good luck Quote Link to comment Share on other sites More sharing options...
arthur Posted October 13, 2004 Report Share Posted October 13, 2004 (edited) as root, type lsmod and the module via82cxxx_audio should be there. if snd_via82xx is also there, type modprobe -e snd_via82xx to unload it. then, can you post the output from 'lsmod' here?

So I switched back over to OSS using harddrake and re-added "via82cxxx_audio" into the modprobe.preload file. I went ahead and modprobe -r'ed the ALSA drivers, but it said they weren't in the kernel, so they're definitely not there... That lsmod is the results, after a restart. The module's loaded properly, right?...What else should I do? Quote Link to comment Share on other sites More sharing options...
arthur Posted October 13, 2004 Report Share Posted October 13, 2004 well, is the sound still crappy without ALSA but with OSS? *cross fingers* Quote Link to comment Share on other sites More sharing options...
volfro Posted October 13, 2004 Author Report Share Posted October 13, 2004 Both. It's not just crappy...It's un-listenable. Just like earlier, it skips so severely that it takes a looooong time for even just the logon sound to complete. XMMS freezes when I try to play music. It's been doing this since I installed MDK 10, and I upgraded hoping the later kernel would fix it... When I updated the ALSA drivers, the problem was somewhat less severe--i.e. still unlistenable, but it played slightly more of the sound at a time, instead of just blips. And no matter the buffer size i choose using KDE's sound system, the problem stays pretty much the same. I don't understand! What can I do?

arthur Posted October 14, 2004 Report Share Posted October 14, 2004 i don't understand how you could update the ALSA drivers separately from the kernel...but anyway, bleeding-edge kernels supposedly have some improved VIA chipset support. You might want to try them. You can try to find out which drivers Knoppix loads on your computer (do lsmod in Knoppix) and which kernel it uses. Unfortunately sometimes everything seems the same but the sound still doesn't work or is too faint, which was my case, prompting me to dump mandrake in favor of gentoo. Debian is also a good candidate since Knoppix was based on it, as well as Ubuntu. Quote Link to comment Share on other sites More sharing options...
volfro Posted October 14, 2004 Author Report Share Posted October 14, 2004 (edited) There were instructions for installing the drivers on alsa-project.org, but the VIA section seems to be down, or I'd send you a link. But they're modular sound drivers, they're not part of the kernel...at least I don't think. I'm still a noob, as you can probably tell. Should I go Debian? Or Gentoo? I don't know if I'm advanced enough for either of those... You're right, though, I should try a newer kernel. I tried before and had problems with make modules_install. I couldn't get it to work. But I will try again. And I'm pretty sure Knoppix uses the OSS drivers, but the edition I have is the older 2.4 kernel. Is it wise to downgrade? I went ahead and did lsmod in Knoppix...

arthur Posted October 14, 2004 Report Share Posted October 14, 2004 actually in mandrake you can install a kernel the easy way. just add a Mandrake Cooker ftp mirror in Media Manager, then urpmi the kernel. You can find more info HERE. it's a bit old, but still an excellent easy guide. Hopefully you'll find the 'Cooker' or 10.1 folder and be able to get a newer kernel. :) Once you've got Mandrake mastered, other distros will be a breeze to learn. Even if I'm not using it anymore, it's an excellent distro. Quote Link to comment Share on other sites More sharing options...
volfro Posted October 14, 2004 Author Report Share Posted October 14, 2004 (edited) That's cool! I didn't know you could do that. But alas, I couldn't find a later kernel for 10.1. Every time I tried to access the mandrake-devel folders, I was denied access. I think it's running 2.6.8, but the latest 2.6 is under the Mdk 10 directory, and it's 2.6.3. Are there any other sources I could go to for that? Edited October 14, 2004 by volfro Quote Link to comment Share on other sites More sharing options...
arthur Posted October 15, 2004 Report Share Posted October 15, 2004 you can go to www.mandrake-linux.com and look in the cooker section (or ftp section, but cooker is newer)...they have all the links there. B) Quote Link to comment Share on other sites More sharing options...
