Hi everybody
I still have sound problems: When I play wave files I get dropouts with my
Creative Soundblaster 128 PCI
exactly in the same way as with the SB 16 Vibra I used before. The Creative Soundblaster 128 PCI is equivalent to the Ensoniq AudioPCI. The dropouts happen as before also with light load. With more load it is easy to reproduce. For example with:
penguin> play some_music.wav & penguin> find / -name "*core*"
Xosview shows the interrupt lights for the timer, sound and scsi controller on both cpus all the time. During the dropouts both interrupt lights for the sound get dark but the lights for the timer and the scsi controller stay on. Also the mouse seems to respond quick. And you can also see the mouse interrupt lights sometimes. The cpus do almost nothing during this test.
Here is some information about my interrupts: CPU0 CPU1 0: 13015 12926 IO-APIC-edge timer 1: 183 167 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 5: 11129 11134 IO-APIC-level es1370 10: 0 0 IO-APIC-level eth0 11: 10478 10479 IO-APIC-level aic7xxx, aic7xxx 12: 1676 1688 IO-APIC-edge PS/2 Mouse 13: 1 0 XT-PIC fpu 14: 1050 180 IO-APIC-edge ide0 NMI: 0 ERR: 0
The pci information about my soundcard is: Bus 0, device 9, function 0: Multimedia audio controller: Ensoniq AudioPCI (rev 1). Slow devsel. IRQ 5. Master Capable. Latency=64. Min Gnt=12.Max Lat=128. I/O at 0xd400 [0xd401].
Does something turn only the soundcard interupts off for some time. All other things work good during the dropouts. The system is also responsive.
Some Information about my computer: Kernel: 2.2.3 (no patches) (SMP) Sound module: es1370.o Distribution: Suse 6.0 Motherboard: Gigabyte 686BXDS Processors: Two Pentium II 350 Mhz Memory: 128 MB (100 Mhz) Scsi controller: Adaptec AIC-7895U Rev: 4 Cd-rom drive: PLEXTOR PX-40TS Rev: 1.00 Harddisk: IBM DDRS-39130W (9100MB) Rev: S97B Graphic card: Matrox Matrox G200 AGP Rev: 1 Sound card: Ensoniq AudioPCI (=SB 128 PCI) Rev: 1
