7 As I said, you're doing it wrong. No "normal" (average desktop, media
8 center, laptop, linux-phone) user needs 10ms of latency in audio.
9 That's overkill. Yours is a special case, and you need special
10 software. Try Jack.

12 And it doesn't need to be in kernel space, by the way. OSS4 is dying
13 because of that.

15 For the rest of us mere mortals, PulseAudio Rocks; it has *variable*
16 latencies by design, so the audio processing doesn't eat up all the
17 battery life. Again, read the comparison between PulseAudio and Jack:
