 Posted: Tue May 11, 2004 4:45 am Post subject: I have let my sound blaster 16 PnP work with alsa |
 |
|
Sound blaster 16 PnP is a devil  under linux thought it sound is nice. I spent 3 days to let it work.
At first U should flow http://www.gentoo.org/doc/en/alsa-guide.xml
I suggest use kernel-dev-sources(2.6).
select 'Sound Card Support' alsa sound building it as a module (M). also select sound blaster 16 building it as a module (M).
build your kernel.
then
dont need emerge alsa-driver. Because you have build it as a module (M).
| Code: |
emerge isapnptools
pumpdump -c >> /etc/isapnp.conf
isapnp /etc/isapnp.conf
nano -w /etc/modules.d/alsa
|
modify /etc/modules.d/alsa
| Code: |
...
alias snd-card-0 snd-sb16
....
options snd-sb16 index=0 id="SB-16" port=0x220 irq=5 dma8=1 dma16=5 isapnp=0
|
the port irq dma will list after isapnp /etc/isapnp.conf
after u | Code: | | modules-update && /etc/init.d/alsasound restart |
congratulate if u card work 
dont forget
| Code: |
rc-update add alsasound boot
rc-update add isapnp boot
|
But these questions puzzle me,
1. I have build isapnp in kernel. why still need merge ispnp?
2. why set isapnp=0? |

Usually even with kernel based facilities like alsa, you still need to use utilities to configure these features. This is also true of pcmcia devices.
I am very excited to hear you got the sb16 working under linux. I have a 100% Soundblaster Compatible card that I am going to try to get working using your instructions. I have had no problems using the oss driver (sb), but it would be interesting to be able to unify everything under alsa.
Thanks for posting your attempt

I believe that line
| Code: | | pumpdump -c >> /etc/isapnp.conf |
should read
| Code: | | pnpdump -c >> /etc/isapnp.conf |
Thanks for the nice help file. |

Hmmm i spent the last three days trying to enable sound without any luck.
And I know it should work because it works under Knoppix.
(Or does Knoppix uses OSS?)
| Code: | bash-2.05b# modules-update && /etc/init.d/alsasound restart

Found the problem:
| Code: |
# pnpdump -c >> /etc/isapnp.conf
# isapnp /etc/isapnp.conf
Board 1 has Identity 6d ff ff ff ff f0 00 8c 0e: CTL00f0 Serial No -1 [checksum 6d]
CTL00f0/-1[0]{Audio }: Ports 0x220 0x330 0x388; IRQ5 DMA1 DMA3 --- Enabled OK
CTL00f0/-1[1]{Game }: Port 0x201; --- Enabled OK
|
Here I noticed that the output I recieved resembles the options line I set in /etc/modules.d/alsa:
| Code: | | options snd-sb16 index=0 id="SB-16" port=0x220 irq=5 dma8=1 dma16=5 isapnp=0 |
Only the "dma16=5" had to be changed to "dma16=3" for my card:
| Code: | | options snd-sb16 index=0 id="SB-16" port=0x220 irq=5 dma8=1 dma16=3 isapnp=0 |
I see now what you ment by : "the port irq dma will list after isapnp /etc/isapnp.conf" 
Thanks! |
