I have installed an SB AWE 64, kernel is 2.4.17, audio works fine, but I
cannot play
simultaneous multpile wav or mp3 files, errors reported that something
else has the device open already.
Here's what syslog reports when the modules are loaded:
Dec 29 13:21:13 ws kernel: Soundblaster audio driver Copyright (C) by
Hannu Savolainen 1993-1996
Dec 29 13:21:14 ws kernel: sb: Creative SB AWE64 PnP detected
Dec 29 13:21:14 ws kernel: sb: ISAPnP reports 'Creative SB AWE64 PnP'
at i/o 0x220, irq 5, dma 1, 5
Dec 29 13:21:14 ws kernel: SB 4.16 detected OK (220)
Dec 29 13:21:14 ws kernel: sb: 1 Soundblaster PnP card(s) found.
Is there some module option to enable duplex operation?
Please CC: me on replies as I am not on this mailing list, thanks.
It is impossible, as I know. For this use either esd (from Enlightenment),
either the same sound daemon from KDE. First seems to be better, because
more supported.
Best regards.

This is an hardware limitation. AWE series don't support multiple PCM
streams.
So mixing multiple PCM streams must be done in software. Use either esd,
artsd, ...
You could imagine a driver based software mixing but :
- it would make drivers far more complex -> more bug-prone,
- it may pose performance/feasability problems when your apps need
accurate timings (Video/audio sync for example).
