Hi, when a sink is started, there is some delay before the first sample is really played. This delay is a constant part of the sink latency that will be always present, so the minimum sink latency cannot go below that start delay. Would it be acceptable to adjust the latency range for the device after each unsuspend to reflect that? USB devices (those I have access to) for example have a startup delay in the range of 10ms, but have a latency range that starts at 0.5ms which does not make a lot of sense in my opinion. The startup delay is not constant, so the minimum possible latency would vary. On the source side the startup delay is not relevant since it does not delay the signal. Regards Georg
