transcoding BBC has streams

RE: transcoding BBC has streams
Please try changing aac:wav to aac:wav-10MB. It might be that the renderer is trying to process the complete "file" in some way before playing it. If so, this will produce a 10MB "file" which should be small enough for the renderer to handle.

Another thing you could try is changing aac:wav to aac:L16. For this, you might need to adjust the playlist by changing [*R3] to [*R3;aac,48000] so that the renderer receives the correct sample rate.

Thanks for these ideas. Unfortunately they don't make a difference, except that aac:L16, after a pause, streams an unimaginably awful high pitch jumble of unrecognisable noise. Log of that attached.

And that aac:L16 is shown as PCM 22.1khz on the renderer display and 44.1khz on the DAC (!)

The log looks normal. It appears that the renderer can't handle an L16 stream.

Just to say that you were right in suspecting that a problem with the network was causing the delay of 16 seconds in streaming the BBC stations: after a recent fault my BT hub seems to have changed setting to assign addresses, which meant there were two devices on the network doing that. I've got rid of that problem, and the delay has gone - it is now pretty much instantaneous.

But sadly it doesn't change the renderer's refusal to play the aac stream when transcoded. I'll let you know if exaSound has any ideas.
