I just upgraded to the current stable KDE 3.2. After starting KDE, KMixCtrl crashes. It seems to be looking for an ALSA configuration, which I removed a while back. I've gone into the Control center and turned off autoloading the mixer when starting KDE. I've also tried the different hardware configurations (it was on autodetect) without success.

Anyone tell me what I've missed or know of a workaround to get the sound to work in KDE 3.2 without using ALSA?

AFAIK, everything else seems to be in order. Here's some of my info, along with the backtrace:

I had to un-install KDE 3.2 from both my Slack boxes, the aRTS sound server would not work properly without AlSA, and ALSA make my SB Live Card sound like crap. Without ALSA installed the aRTS hog ties the /dev/dsp and /dev/mixer so I was not able to use the emu10k1 driver, So I put KDE 3.14 back in and all is well.......my SB live card works like it's supposed to......with the emu10k1 driver.

Try changing Control Center -> Sound & Multimedia -> Sound System -> hardware -> audio device to Threaded Open Sound System. I did that and it worked fine.
Just make sure that you compiled in OSS emulation.

I tried that in Control Center, but then I don't remember if I used OSS emulation............I don't think so since my card was listed before the section for OSS emulation...........hmmmm...........I'll have to double check that. Thanx

I'll let you know how it turns out

Hey ghostwalker,

One question..................should I disable the driver in the kernel config and use strictly OSS emulation, or just go ahead and use the emulation on top of the driver?.........I'm thinking about possible confilicts happening

Well, it seems that I already compiled the OSS modules for the SoundBlaster compatible (sb.o) besides the emu10k1 driver, so I'm at a loss............................after looking at the kernel config (v2.4.24), I didn't see any "OSS emulation", only "OSS modules" in the Sound section, which is what I thought was being referred to................Is there an emulation option located somewhere else besides the Sound section?


--------------------
PS: I also tried to modprobe the sb driver, but it didn't work. Here's the output:
Code:
 # modprobe sb
/lib/modules/2.4.24/kernel/drivers/sound/sb.o: init_module: No such device
/lib/modules/2.4.24/kernel/drivers/sound/sb.o: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.24/kernel/drivers/sound/sb.o: insmod /lib/modules/2.4.24/kernel/drivers/sound/sb.o failed
/lib/modules/2.4.24/kernel/drivers/sound/sb.o: insmod sb failed
And yes, there _is_ a sb.o driver located in the drivers/sound directory.........

Ummmm.............................hehehe, it seems that it was pilot error as the reason the sound wasn't working......................After messing around inside my computer, I had plugged the speakers back into the wrong plugin.......*slaps forehead*...........anyway, the sound is now working. I have the hardware settings on autodetect and it works just fine.............................Thanx anyway and sorry for all the trouble

Hi

some thoughts on kmixctrl and alsa and sound not using alsa.

1) Plse check your /etc/hotplug/blacklist file.....you may need to remove some files that hotplug are ignoring for me they are
sb sb_lib uart401 sound soundcore etc

2) In your home directory is a file called dot xsession-errors (for slackware 10) and I have had errors.You may need to see "hidden" files.
This file when I had kmixctrl errors alerted me to the
/tmp/mcop-your name/ file (I can't remember) but after I deleted the lot from here my warning disappeared.

3) And other posts suggest there is an issue with kde sound server not releasing after running an arts (sound ) file, so I disable sound server for kde in the control centre area.

4) Some people may not have UNcommented there card stuff in /etc/rd.d/rc.modules......which is where I enable my sb card.


hope that helps
