I have a Delta 66 in an Abit BH6 board that gets ticks and pops when playing mp3's and doing anything video like dragging a window around or even selecting a message in knews. Even having gaim pop up a message, no sound on, may cause a tick or pop or stutter. Mandrake 8.0 with the version of ALSA (rc2) that ships with it. BH6 with 1.2ghz PIII and 512mb, no irq conflicts and I have tried both the dedicated PCI slots and the shared slots and even tried forcing an irq to the slot. It does the same thing with an Nvidia, ATI or Matrox AGP card installed and the driver doesn't seem to matter. I have also tried both enabling and disabling a video irq. I also disabled the arts sound driver and turned off system sounds. BTW the first slot shares IRQ's with the AGP card so I didn't even consider using that one :) I have turned off all eye candy and played with the buffers and other settings in xmms and Zinf. Using the OSS plugin for xmms works a little bit better than the alsa output plugin, but both are mostly unusable. I have DMA and all the other performance things turned on for the hard drives, but it is the same with out them. It is definately video related. Just for kicks I tossed a Soundblaster 128 PCI (Ensoniq chipset?) into the system and it plays back fine even with all the eye candy turned back on so this is definately an issue with the Delta driver. I also tried my 1010 which gave me the same exact troubles. Both cards work fine under Windows. I don't notice any activity via gkrellum, or the hard driver lights or CPU load or anything when it fails. One thing I noticed is that under kde control panel it says : Installed driver: Type 10 Alsa emulation. In conclusion, this acts just like the classic video card hogging the pci bus problem we used to have under Windows before AGP cards were availible. Does anyone have any ideas? I would like to experiment with JACK and such, but if I can't get a pro level audio card to function playing an mp3 I won't be able to.
