Soundcard "Acer Labs M5451" not working (interrupt timeout)

[Pillon Matteo]

Hi!

I have some troubles with snd_t4dwave driver. FreeBSD is running on a
Compaq Presario 2532eu notebook with an ALi M5451 soundcard.

scanpci:

snd_t4dwave gets loaded without errors:
 pcm0: <Acer Labs M5451> port 0x1000-0x10ff mem 0xd0000000-0xd0000fff

But when I try to play or record something, I get an interrupt timeout error:

I also tried Ariff Abdullah patches without success.

Any suggestion?

I tried searching the archives, but this problem is different from
others, as no data is played/recorded since boot.

Thanks.
Bye.
