RE: no sound with CS4281 card

[Woller, Thomas]

I'll send the latest driver that I have via separate email.  Toshiba refuses
to supply equipment, and there are some design issues with Toshiba laptops.
I recently sent a driver to another Toshiba owner and he had good luck with
the latest driver. I have never seen any Toshiba laptop not generate sound
with any cs4281 driver at any time ( :) ), but that certainly doesn't rule
out the 2.4.5-ac2 not working on a Toshiba 1755.  I am pulling the 2.4.5-ac6
source now and will try on a 4281 ref card.  
mpg123 the only app not working?
Thanks for the input
tom

Hi,

my notebook (Toshiba 1755) comes with CS4281 built-in,
with all 2.4 kernels I tried this sound card doesn't
generate any sound, or interrupts for that matter.

The driver detects the card fine, but doesn't seem to
be able to do anything with it, on 2.4.5-ac2:

==== /proc/pci ====
  Bus  0, device   8, function  0:
    Multimedia audio controller: Cirrus Logic Crystal CS4281 PCI Audio (rev
1).
      IRQ 5.
      Master Capable.  Latency=64.  Min Gnt=4.Max Lat=24.
      Non-prefetchable 32 bit memory at 0xfc010000 [0xfc010fff].
      Non-prefetchable 32 bit memory at 0xfc000000 [0xfc00ffff].

==== dmesg ====

==== /proc/interrupts ====

(after trying to play music with mpg123 about 20 times)

It turned out a one-liner change to the in-kernel driver
also worked (I was on holidays for a week, so I only see
this email after I got the thing to work ;))

I Can not reproduce the problem with 2.4.5-ac5 driver or with latest rev of
the driver that I have been working on, or with any of the previous 4
internal releases back to early april.  although I do not have a Toshiba
laptop to test on and don't doubt that there might be a problem on your
system.  I have not tested a 1755 model.  Another user indicated that the
Toshiba 1620 CDS works with the latest driver.   
I'll wait for your input concerning the latest driver that I sent to you via
email.  Fyi, I have USB disabled, SMP enabled, and all *PM enabled.
If you can boot with max debugging
/sbin/insmod cs4281.o cs_debuglevel=9 cs_debugmask=0xffffffff
and then run mpg123 on a very small mp3 file or very small wave file (<16k).
It'll be a lot of output, but if you could send it all, especially the boot
info, that'd help me to debug the problem.
Thanks
tom
