I just cannot figure this out. I have an IBM ThinkPad 1412, Celeron 366, 96MB Ram, ESS Solo1 soundcard. The sound NEVER works if I just install default Mandrake kernels. It loads modules, even the correct modules, but sound never comes - so I always build my own kernels with the solo1 driver built into the kernel.
I get sound working temporarily with kernel-2.4.8-34.1mdk and with kernel 2.4.17 from kernel.org (cannot get the Mandrake 2.4.17 kernel to work even though I can get it to build - always with the "kernel panic: VFS unable to load root fs at 01:00" no matter what settings I make in xconfig). When I first startup and login, sound works (KDE 2.2.1). After some period of time between 30 minutes to an hour sound no longer works. There are no error messages, no sound-related messages ANYWHERE to indicate that there is a problem. Sound just quits. I have looked in /var/log/messages, .xsession-errors (with and without debugging messages enabled with artsd) and nothing ever presents itself to explain the loss. I have run into another situation while sound is working that I don't know what to make of, nor do I know if it is somehow related. I have a wireless lan card (ZoomAir prism2) and several wlan sniffing/monitoring apps. Kismet is a nice one - it logs all detected wireless lan traffic with network names, whether or not wep is enabled, and lots more. It also has a couple wav files associated with it - one sound to indicate a new network was detected and another sound to indicate lan traffic. While running kismet, the sound is working OK but then, periodically, a high-pitched squeel comes form my speakers and the cursor freezes. It takes about 5 seconds when a message pops up "CPU overload, artsd aborting" at which point the system functions normally again WITH sound...but then I get messages indicating that artsd was unable to connect to server /tmp/mcop-praedor<some-mcop-file-name-string>. Another thing that I am still trying to determine if it is a player in the problem is APM and/or the screensaver. If I come to my laptop after the screen has blanked in power save mode (~30 minutes), I have found that sound is no longer working. Logging out and logging back (restarting my kde session) wont bring it back. The only thing that brings it back is a full reboot. I have also lost sound, on a couple occasions, when I close the laptop with while it is still running. Everything else that is going on (compiling a kernel or something else) continues OK but it seems that sound gets lost. I just cannot be certain at this point if sound was lost 1) before power saving went into affect; or 2) if it was lost prior to my closing the laptop lid. In none of these situations has any sounds been playing at the time of the system change. If I open up kcontrol and restart the soundserver, it restarts OK and .xsession-errors doesn't indicate any problems (I have debugging enabled now) - it actually indicates that the soundserver restarted OK and that the sound was actually played (no it wasn't). My sound mixer has all the appropriate volume settings set properly too. Anyone have any ideas here? _________________________________________________________ Do You Yahoo!?
