Okay, whoever says ALSA is greater than OSS, I'm trying to act on your assertions, so here are a few questions.
I have the primary PCM configured with silence_threshold set to zero and silence_size set to MAXINT. This condition is documented as "The whole ring buffer is filled with silence at start. Later, only just processed area is filled with silence." When is "start"? Is it snd_pcm_prepare, or snd_pcm_start? If it's the latter, it's not too useful, as I currently snd_pcm_prepare, fill the mmap buffer with sounds, then run snd_pcm_start. Right now when I do that, the beginning of the sound effect that triggers snd_pcm_start is silent (but more gets streamed into the mmap buffer later on, and that is heard). With ALSA's oddball mmap scheme it's not like I could just easily do the silence processing myself, so it would be nice if ALSA's would do the right thing. And is there a way to query what the current application frame position is, without tracking it myself? Have to do a lot of rewinds (and forwards) here to add more sound effects to the mmap buffer and such, and being able to sanity-check the offsets would probably be nice. And for sound cards capable of hardware mixing, is there a way to have two PCMs that share a buffer, but can be still be started and stopped independently? For example, if I've loaded an explosion sound into a PCM buffer, how can I start a lot of explosion sounds, without wasting a lot of RAM? Perhaps there's also a way to specify that this sound should be loaded into the sound card's onboard memory, instead of streamed from system RAM? ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
