It now seems pointless using our OSS code if its then going to be emulated by ALSA. I'm sure if i stick with ALSA i can get real nice results, its just a steep learning curve for ALSA n00bs like me... :( If I was writing a basic audio app with little consideration for latency and efficiency i'd probably have stuck with OSS and ALSA emulation... The main feature i'm interested in is the asychronous pcm playback, it means we can setup the sounds mixer, and not have to worry about calling an update_sound() function every 1/20th of a sec... > > _Dont get me wrong_, ALSA is great and a lot more powerful than OSS, but it is > lacking a simple API. > Ever try to write an In/Out volume control mixer in OSS?
