That said, the incorrect values are rather the "avail", that is the PCM position, not the timestamp itself, I suppose. Is it only about recording, i.e. playback doesn't show any wrong values? In anyway, try to enable the tracing for snd_pcm, get the position and the system timestamp during recording, and verify whether the reported values are reasonable or not. Takashi
