See, this is exactly the problem of the SD ranters. A ranter posts a
problem, doesn't give reproducability hints, and neither provides technical
detail, not even the slightest relevant stats. And the most irritating
part is that the code that the OP wrote (or at least its relevant parts) is
not even available for download.
I was wondering why the OP need timers for audio playback. What type of
audio? PCM, MIDI? Once does not need timers for PCM playback but for MIDI.
SD ranters. Pure rants.
Thank you very much.
Best Regards,
Carlo

actually, there was no "SD ranting" going on at all. Klaus reported a
problem, Martin forwarded it to me, i replied to it and Klaus gave me
lots of debug info in a very professional way. So please calm down and
lets get back to the tech topics, ok? (and i'd like to apologize here to
Karl and Martin for the rough and unjust treatment they received on
lkml.)
