I tried to get "latency" example from ALSA to work (it basically records audio, pauses for a while, then plays it back) on N900, and all I'm getting is silence... plus now it oopsed. Any idea? Is there any version where audio recording works? What do you use for testing? Are there any mixer settings I should know about?
