Hi, I have spend almost weeks on this but not luck. I have tried
via82cxxx_audio.o which come from standard linux kernel and alsa via686a,
but modules seems to load but give no sound.
when I try to load snd-card-via686a, it gaves out a poping noise just like
speaker poweron, then nothing comes out if play something, no error message
too. Is that an IRQ problem or EAPD problem? I have seen people talk about
this identical laptop here but no further messages anymore. You help are
greatly appreciated!
tried 2.4.18-pre9, 2.5.2-pre10, which are only two stable kernel run on my
laptop. APM on, ACPI and APIC off. I am currently suspect that it is an IRQ
problem since in my /var/log/messages:
