Aborting. > === end === Umpf. there seems to be something very broken here in the audio driver or alsa-libs. We only support interleaved channels. This assert above is always true for interleaved channels. We ask the ALSA driver for interleaved channels. But apparently it gave us some more complex channel arrangement. Please report to the ALSA people. But first try to update your kernel driver and alsa-libs to newest from upstream.
