GUS MAX problem

GUS MAX problem

[Benoit Rouits]

Hello,
(I'm not subscribed, please use reply)

I've got a problem with my 2.0.31 kernel
 and standard driver for GUS that is :

-When i use MIDI player first time, i get a segmentation fault. At the 
second time, the /dev/sequencer is said BUSY.But when i CAT foo.bar in /dev/
sequencer
, I can "hear" some midi message.(unsynchrnised of course) What's the 
problem?

- Secondly, wave sound works well but sometimes i get a big BUZZ when 
playing some file. I'm forced to reboot to get good sound again.

Any suggestion?

Thank's a lot .

P.S: My GUS MAX is an ISA one and works
 well under Micro$oft and I'm sure to not have any irq or dma conflicts.

I have also GUS MAX 512k and it has always worked fine. But I have very
rarely used the standard Linux sound drivers, because I have found that
Linux Ultra Sound Project drivers work better. You might try them

http://home.pf.jcu.cz/~perex/ultra/

There's also ALSA project, but for me the Ultra drivers work better.

I'm using kernel 2.0.36 right now but everything has worked fine with
few older kernels too.

You might try giving commands
 cat /proc/interrupts
and
 cat /proc/ports
and
 cat /proc/dma
(if i remembered the file names right. if not, peek around under /proc
directory).
They should help resolving irq/dma conflicts _if_ you have one. But if
you're sure it's not a conflict, you can ignore this.

Anyway, my GUS has DMA 5 and 6 and IRQ 11 and port 220h.

GUS MAX problem

[Benoit Rouits]

Hello again,

Thank you for the adress of the GUS Project that you gave me.I tried again 
to look for irq problems but did not found it, so I will use now the 
"Perex's driver" because i can't do anything with the standard one.And this 
old one do not manage really aGUS MAX (ie: 16 bit recording and 32 
polyphonic voices) but a standard GUS thatis a 8-bit sample card. So, now i 
will be able to use TRUELY my GUS MAX.I also got the irq 11 for it but i 
added
 irq 5 for the midi features and DMA 1 for output and DMA 3 four input 
audio.

I'msurprised that you did not mentionned
 the midi irq in your reply: is it because this is unused? or because this 
mustbe the same as Gf1 irq? (i.e: 11 for me)

Maybe it is the reason for why my midi output doesn't work...I will try irq 
11 for all the sound card
.
bye ! Benoit.

The standard Linux sound driver (also called as OSS/Lite or just OSS, Open
Sound System) should support GUS MAX too with all 32 voices and 16-bit
recording.

Why I like more Perex Ultra drivers? Because it allows full-duplex sound
between different programs (start one program which plays digitized sound
and then you can start another program which can record digital audio).

It also has UltraMIDI, which can play MIDIs and nice Tcl/Tk GUI mixer.

Both drivers should support GUS MAX and not only classic GUS.

Hmm. I can't check right now but I think that you can not even tell the
driver what secondary IRQ to use. I think that the second IRQ is mainly
meant for SB emulation and has no use in Linux.

When you set up OSS (using make config/menuconfig/xconfig) you should
not select "General MIDI" or whatever the option was called... it
would allow you to select another IRQ, but this option is not meant
to be used with GUS.

(However, OSS worked althought I ignorantly selected the General
MIDI and second IRQ at first).

You should use DMAs higher than 3. DMA 1 and 3 are only 8-bit wide, while
higher DMAs are 16-bit and should work at least little faster.
