Hi all,

I recently wrote a block for decoding DRM AAC streams. For testing I put together a small flow graph consisting of a wav source, encoder block, decoder block, (rational) resampler and an audio sink (an image of the flow graph is attached).

When I now run this flow graph, the audio is correctly decoded, but the output is not throttled to 44.1 kHz as it should be. It seems to be running at full speed. I also connected a resampler and an audio sink directly to the wav source and there the output is correct.

I use default values for the audio sink (alsa, 44.1 kHz), GNU Radio 3.5.1 and xubuntu 11.10.

Any hints why this is happening and how to solve this?

Best regards,
Felix Wunsch
