Hi list,
This is (possibly) not the same issue as in the recent "Laptop CD Audio" thread.
I have a Sony Vaio PCG-Z1XSP which I like a lot, but which has a
problem with audio. It doesn't matter if the audio is from a CD, a
DVD, an MPEG file or some other source, it's always the same problem:
Unless there is traffic on the network interfaces, or on USB (e.g. I'm
moving my USB mouse around constantly), the sound grinds to a halt
after a few seconds.
I noticed that USB (uhci0, uhci1), network (fxp0), and the sound
driver (auich0) all uses IRQ 9. There is no way to modify this
through any BIOS settings. Just as on the Dell Inspiron 1000 of
Christian (in the other laptop audio thread), BIOS configuration on
the Vaio is incredibly limited. On this machine, "advance BIOS
settings" includes turning the Vaio logo animation on powerup on or
off...
My attempts so far has only included trying the fixups from
pcibios(4), but to no avail. Any other suggestions welcome.
Regards,
Andreas
