[linux-audio-dev] Low-latency patch of the moment

2001-12-10 Thread Anders Torger
Is there any good source of information when it comes to choosing a low-latency patch for a 2.4 kernel? Some of the low-latency patches I have tested does not work very well (perhaps my SMP machine is the problem?), so I just wonder, perhaps someone knows which ones to use? /Anders Torger

, but only for clocked devices (that is sound cards), since I thought for transfers to files or between applications these first null samples would be seen as junk and should rather not be there... but I suppose it is the price one has to pay. /Anders Torger

[linux-audio-dev] Performance problems caused by dlopen()

with only this scarce information, however, if anyone know about general performance problems caused by loading dynamic stuff into the software with dlopen(), and how they should be avoided, I'd be glad to know. Oh, I use a 2.4.17 kernel, low-latency patched. /Anders Torger
