   [OpenAL]You can't start multiple sources at the same time?!
for(i=0;i<5/;++i){add_sound_object( i,0,0);//Sleep(100);}After struggling for some time I've figured out what's wrong with my AL implementation, and it is very suprising. In the code above, add_sound_object loads samples for the specified sound type (if required) and queues them against the first unused source in a list. The code shown will result in errors in alGenBuffer and alQueueSource - however if I uncomment the Sleep call it works fine!I'm not using any threads so nothing in my code will be affected by this change - I can only assume that trying to queue/load too many things at the same instant knackers AL's internal threads or something... can anyone corroborate?   
  Don't the errors give you any further details?   ;  I get the error "Invalid Name" from alGenBuffer. This is just plain wierd...   ;  When you say it works when Sleep() is called, does that mean the errors go away or the sound plays or both? I have not had any problems loading and playing multiple buffers.Could you post some minimal source that replicates your problem? It would also be helpful to see what's in your add_sound_object() function.What are the size and count of your buffers and how many sources play at once? I don't know what your computer specs are but if it is really slow((less)400Mhz) that may be a problem.It's very strange that alGenBuffer() would generate an INVALID_NAME error. Make sure you log the value of alGetError() after every OpenAL call.Oh, and from your other OpenAL thread, playing 7-8 source at once shouldn't be a problem for a reasonable computer.   ;  The source is quite complex...I'm playing maybe 5 sources at the same instant, each being queued with 2/3 buffers. With Sleep() enabled, there are no errors and the sounds play. Without it, some of the sources get errors (not all).The PC is 750MHz. Do I need to use a Mutex/Ctitical Section with AL if my app is single-threaded - the original source did this but it seems un-needed.   ;  I don't think you need any of those things. You must be working with some pretty wierd platform/source:) I'll share my audio code. It streams .oggs and play wave files. Maybe it'll help somehow.openal_audio.zipGood Luck
