Public bug reported:
I have a 8 hour recording which seems to play fine once if I click any
where and press play. If I stop the playback and I zoom out and place
the marker somwhere else and press play audacity seems to suffer from a
snd_pcm_recover under run and the sound sounds streched with a few
seconds of playback which results in audacity showing that the recording
is in its first minute after playback, say 5 seconds after plyback has
started again. If I pause the playback and resume playback, Audacity
continues with the above. If I stop playback Audacity crashes with
../nptl/pthread_mutex_lock.c:359: __pthread_mutex_lock_full: Assertion
`robust || (oldval & 0x40000000) == 0' failed.
I have tried extracting 2 hours from the 8 hour recording and saved that
as a seperate Audacity Project and I still get the crash mentioned
above.
Running audacity from the command line and repeating the above, I get a
few errors on startup and the above problem errors on the CLI (see
attached CLI error messags.txt)
I am able to reproduce this all the time, so I am going to see if I can
get more debugging information to resolve this.
