I have nstalled audacity from your PPA. 2 scenarios:

1. First start audacity then start jackd.
Audacity and jackd are running. During recording in audacity audio
cursor jerks at the beginning of audio snippet and then (sometimes)
following message is shown:
"""Latency Correction setting has caused the recorded audio to be
hidden before zero. Audacity has brought it back to start at zero. You
may have to use the Time Shift Tool (<---> or F5) to drag the track to
the right place."""
So I can not record any sound (without started jackd it works)

2. First start jackd then start audacity.
Jackd dies right after audacity is started audacity is still running.
After audacity is closed assertion failed is reported. Console output
is

$ audacity
Expression 'ioctl( devHandle, SNDCTL_DSP_CHANNELS, &temp )' failed in
'src/hostapi/oss/pa_unix_oss.c', line: 405
audacity: src/hostapi/jack/pa_jack.c:813: Terminate: Assertion `aErr_
== 0' failed.
Aborted
