Alsa 2 error message

I work with QNX 4.25 and I’d would like to install a PC 104 sound card
(Crystal-MM-HP of Diamond Systems Corporation). The AudioDrive chip is
an ESS1869F with is sound blaster compatible. Moreover the installation
works since it works under DOS.
So, I’ve just downloaded the alsa 0.2 audio driver binaries.
To load the driver, I tape :
deva-sb -p220 -i11 -d0,1
And under /dev, I have the following new devices :
midi00
mixer00
pcm00 sndctl00

Then, I try to play a wave file, using aplay :
aplay filename.wav
The out is :
Aplay : version 0.0.8 by Jaroslav Kysela <perex@jcu.cz>
Error : audio open error : Ressource busy

I tried a lot of things but nothing goes right…

Thanks for your help,

Hi,

This is just a shot in the dark, but I can see two things
in your posting which you might might be causing your problems.

  1. Using DMA channel 0 will conflict with the QNX4 NE2000
    driver. In general, it is best to avoid using DMA channel 0
    on QNX4 for audio (or anything but networking) if there
    is any chance that you might run a network driver.

  2. Are you sure that you have the correct options
    (port, irq, dma)? I assume that this is a Plug-and-Play
    card (not jumpered). If that is the case, I would recommend
    that you download the isapnp.tgz archive from /usr/free.

ftp://ftp.qnx.com/usr/free/qnx4/os/utils/misc/.

There is a bunch of info in readmes and the source is included.
Basically, you use pnpdump to create a config file, edit it
to your liking (don’t use DMA channel 0) and load it using
isapnp.
