Comment:

 Fixed in Record-74

 There are still some unknowns. #10137 is one likely source of bad sync
 (although minimal, since gstreamer's videorate element will cut out most
 of the error).

 The solution in Record was to put a buffer in the audio recording path,
 effectively avoiding some buffer underruns that occurred when starting a
 recording, which were causing bad sync for the whole recording. gstreamer
 looks like it should be able to recover (i.e. resync later on) but this
 isn't working well, possible bug in gstreamer or ALSA.

 and the plughw:0,0 change is still a little unexplained.

 But given that we have a working activity, after some testing we can
 probably close this for now.
