Hi,
I'm still dealing with a legacy free laptop. It looks like the problem
is not going to be solved soon (not even with kernel 2.5).
What' happening briefly is that IRQ are not assigned so they are all
set to 0, so it happens for the sound card.
Now i went for a nasty hack and i hardcoded the IRQ in the kernel
pci_irq.c (specifically set to irq=10)
with the following results:
with the kernel modules and OSS free i can play the CDROM and play the
first fraction of a sound with sox complaining that cannot set the
srate to 44Khz so it goes to 48Khz.
Then i meda a _clean_ kernel for alsa and compiled alsa with the
intel8x0 module. For some reason it does not load at boot time and with a
manual insmod
i got all the modules inserted.
alsamixer, gamix, aumix, xmix, they all work with no problems.
But then when i try to play a sound i get this:
(and no sound of course. the cdrom as well does not work
cdda also reads with no problems but no sound coming out: of course
mixers are set with all outputs to 100%).
[I know, hardcoding is really the worst solution....but right is the
only way to test and to get some sound out of this machine...
Would it help, still speaking in bad terms to set in the same alsa
code the irq to the one i set in the kernel?]
any clue or any hint?
thenk you,
marco trevisani
PS. Below some reports of my attempts.
