Using Ubuntu Studio 12.04, ardour will not rewind when it is set to the jack time master. I've read that this could be due to a jack/ardour version conflict, but I am not sure what the correct combo should be.
The same thing happens with "ardour 2.8.14 (built from revision 13065)" and "ardour 2.8.12 (built from revision 10144)". The latter is the default installation with ubuntu studio 12.04 LTS.
Linux /proc/version reports as
Linux version 3.2.0-23-lowlatency-pae (buildd@vernadsky) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #31-Ubuntu SMP PREEMPT Wed Apr 11 04:07:36 UTC 2012
and jackd --version reports as:
