[9fans] sb16

[9fans] sb16

[gas]

I have an old ISA sound card, identified by win98 as "creative sound
blaster 16 plug and play".
So, I added the line
        audio0=type=sb16 port=0x220 irq=5 dma=1
to plan9.ini and 'bind #A' to termrc, but I got the error
        #A: no response #ff
With the if-statement surrounding that print commented out of
devaudio.c, the next try failed with
        #A: model 0xff 0xff; not SB 16 compatible
I commented out that too and got another pair of error messages:
        i8259enable: irq 2 shared but not level
        intrenable: couldn't enable irq 2, tbdf 0xFFFFFFFF for audio

By then I had /dev/audio etc., but no sound. Any ideas?

In plan9.ini(8) there should be another type - try that instead. If  
that doesn't work, I don't know.

OK, I tried ess1688 now but it's the same "#A: no response #ff".

hi,

if i remember correctly, there are multiple versions of SB16. Some work and
some dont. I have both types. The one that didnt work had another name
called Ensoniq I think (may be that company was bought by Creative).

anyway, my usual suggestion is completely ignore sound cards since they are
so confusing and it is difficult to get them up and running. instead, think
of buying an USB audio device. I have several devices working fine:
something like Edirol UA-1X, Xitel HiFi-Link AN1 and Xitel Pro HiFi-Link.
There are also other devices that are known to work.

here are some links that may be of use:
http://www.tip9ug.jp/who/ziphos/edirol.tests
http://www.infernopark.com/plan9/mad/mad.html

hope this helps.

regards
dharani

If the driver says the card isn't responding, making it
continue on blindly isn't likely to change the situation.
Luckily, the card you have should work, as long as it 
is what Win98 says it is.

On the sb16 plug-and-play, the important field is port=.
The irq= and dma= actually get programmed into the
card (or read from it, if you don't specify them), but
the driver needs a correct port= to find the card in the
first place.

Below is a very old throwaway program I wrote called tsb.c.
I haven't used it in 7+ years, but it looks like it should
still work.  It probes a given port to see if it finds a sb16 there.
If it prints sensible numbers, then it did.

	8c tsb.c
	8l tsb.8
	for(i in 0x220 0x240 0x260 0x280)
		echo -n 'port='$i && 8.out $i >[2]/dev/null

For example, here's a run on a machine without a sb16.

	% for(i in 0x220 0x240 0x260 0x280)
		echo -n 'port='$i && 8.out >[2]/dev/null
	port=0x220 irq:#ff:10 dma:#ff:0 1 3 5 6 7 
	port=0x240 irq:#ff:10 dma:#ff:0 1 3 5 6 7 
	port=0x260 irq:#ff:10 dma:#ff:0 1 3 5 6 7 
	port=0x280 irq:#ff:10 dma:#ff:0 1 3 5 6 7 
	% 

On a machine with a sb16, one of those lines should have hex
numbers other than #ff.  Use that port number.

If you run it without the >[2]/dev/null you'll get more 
debugging info than you could want to see.

Re: [9fans] sb16

Thanks Russ, great!

My random fiddling led me to rip out the other isa card, an elnk3
just sitting there. That didn't help at first, all I got  from your
program
was #ff. Anyway, after booting into windows, deleting the ethernet
driver and rebooting, the program printed #02. Windows must have
done some reshuffling magic, I suppose.

Now it works with 0x220.

Here's an update to the 3rd edition version of /sys/src/9/port/devaudio.c for
sbpro support.  It's been found to work on a real sbpro and at least two
impostors; it doesn't work on the Thinkpad T21.

I think my resampling of sound data in b8to16() and b16to8() isn't quite right.
Would somebody like to comment?

[9fans] SB16

[Carlos Eduardo Lenz]

My laptop allows to enable SB16 compatibility for the VIA soundcard in
the bios.
I enabled it in plan9.ini, with the dma,irq, etc set in the bios.
But it gives the error msg:
#A: model 0x03 0x02: not SB16 compatible (or something similar).

Found that devsound.c tests for major=0x03 and minor=0x01.
So I need to know if I can just add another test that fits my config or
my card isn't really supported?

It's probably sbpro; I've never seen a card that emulated an sb16.

You can't just bung in different major/minor numbers; the sbpro is only
8-bit, so you have to scale down the 16-bit samples first.

There's an sbpro driver for 2nd Edition on Charles Forsyth's Plan 9 software
page.  It may be a SMOP to port it to 3rd Edition.

Re: [9fans] SB16

[Carlos Eduardo Lenz]

It says in the bios setup it can emulate a sb16 (compaq 1200series)! So
it's not true?

Anyway, what are the major&minor about? My guess was that they are values
set somewhere by a real sb16 (for detection).
