CS4236B sound card config fails (midi)
Last modified: 2014-03-16 22:15:58 EDT
Using the CS4236B sound chip (Dell OptiPlex GX1), the sound and midi
examples are played correctly, but on exit the following error message is
cs4232: set synthio and synthirq to use the wavefront facilities
uart401: Failed to allocate IRQ5
(cat /proc/interrups says:
5: 85 XT PIC Crystal audio controller
On system restart the following error message is displayed:
Loading midi module (opl3): Hint: insmod errors can be caused by incorrect
module parameters, including invalid IO or IRQ parameters
/lib/modules/2.2.16/21.4/misc/opl3.o: init_module: Device or resource busy
/lib/modules/2.2.16/21.4/misc/opl3.o: insmod opl3 failed
Is it a PnP card, or does it have fixed addresses?
The card is onboard, the computer is one of the latest Dell machines (1 year
old), therefore I think it definitely doesn't use fixed addresses.
What does pnpdump say?
Created attachment 2838 [details]
pnpdump before sndconfig
Created attachment 2839 [details]
pnpdump after sndconfig execution
Additional notes for the above attachments: this was a CD-ROM server install
(with all the packages necessary for sndconfig installed afterwards). After
sndconfig, the system was not restarted. Could do this if necessary.
Eek, I've been really awful about this. The odd thing is that according
to those dumps, it didn't change the isapnp.conf at all. Does this
persist with the current sndconfig (it hasn't changed much in this
closing, lack of response. Moreover, in current releases this is handled by the
kernel PnP code.
