I tried loading via82xx first with dxs_support=1, then with dxs_support=2, then dxs_support=4 but the same errors happen. For example, while playing: $ aplay -c 2 -f S16_LE -r 22000 music 2216.raw if I move the mouse, the kernel gives error messages: Nov 18 19:55:18 kernel: ACPI: PCI interrupt 0000:00:11.5[C] -> GSI 9 (level, low) -> IRQ 9 Nov 18 19:55:19 kernel: usbcore: registered new driver snd-usb-audio Nov 18 19:55:34 kernel: spurious 8259A interrupt: IRQ7. Nov 18 19:55:47 kernel: irq 11: nobody cared!

The pointer can moved only by using the touchpad. modprobe.conf has: alias char-major-14-* soundcore alias char-major-116-* snd options snd major=116 cards_limit=1 alias snd-card-0 snd-via82xx options snd-via82xx enable=1 dxs_support=1 alias snd-card-0 snd-via82xx alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-12 snd-pcm-oss alias /dev/dsp1 snd-pcm-oss Any suggestions please?
