no, Alsa is not on qnx, but I would like to know if you had to do this using ALSA how would you do it. Not the exact function calls, but just the general idea, i will then try to put it in use in qnx world.
To quote from the qnx audio developers guide: "This whole system is referred to as the QNX Sound Architecture (QSA). QSA has a rich heritage and owes a large part of its design to version 0.5.2 of the Advanced Linux Sound Architecture (ALSA), but as both systems continued to develop and expand, direct compatibility between the two was lost. " A look at http://www.qnx.com/developers/docs/momentics621_docs/neutrino/audio/summary.html might explain why I am saying it is quite similar. If this is very much off-topic, I will understand. But in that case forget that I said QNX and replace it by ALSA. :) Thanks for your time and the reply. cheers! Me Eby <[EMAIL PROTECTED]> wrote: > I was not aware that ALSA was available on QNX.
