Re: [Alsa-user] VIA V8237 problems with snd-mpu401 module

[Edenyard <ma...@ed...>]

Many thanks for your help, Clemens.

I've edited /etc/modules.conf and added your suggested line:

	'alias snd-card-3 snd-mpu401'

just before:

	'options snd-mpu401 enable=1 port=0x330 irq=5'

I've also altered the line that said:

	'options snd major=116 cards_limit=3'

to

	'options snd major=116 cards_limit=4'

but unfortunately still snd-mpu401 doesn't load.

Yes - I find this (twice, consecutively) in /var/log/syslog:

kernel: MPU-401 device not found or device busy
insmod: 
/lib/modules/2.4.31-asr-060602a/kernel/sound/drivers/mpu401/snd-mpu401.o: 
init_module: No such device
insmod: 
/lib/modules/2.4.31-asr-060602a/kernel/sound/drivers/mpu401/snd-mpu401.o: 
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.       You may find more 
information in syslog or the output from dmesg
insmod: 
/lib/modules/2.4.31-asr-060602a/kernel/sound/drivers/mpu401/snd-mpu401.o: 
insmod snd-card-3 failed


I've noticed also that 'lsmod' reveals that a module called 
'snd-mpu401-uart' is getting loaded, but I'm not sure how or why this 
is. I wonder whether the existence of this module explains the 'device 
busy' error message in /var/log/syslog?

I'm still rather at a loss to know what to do to fix this, so I'd be 
very grateful for any further clues you could give me.

Thanks again,
Gerald.
