Audacity crashes at startup when jack is running

[Matthew Koyle]

Binary package hint: audacity

In AMD64 up-to-date gutsy, audacity crashes at startup when qjackctl / jackd is running (it executes normally if jack is not running).

It goes off with an error:

***MEMORY-ERROR***: audacity[6644]: GSlice: failed to allocate 496 bytes (alignment: 512): Cannot allocate memory

Program received signal SIGABRT, Aborted.

In which locale are you running Audacity? It looks like this is an error when trying to draw the menu item, and the apparent relation to JACK vs. not JACK is coincidental.

[Matthew Koyle (mgkoyle)]

I just can't believe that the failure to load when jack is running 100% of the time and success after closing jack just a few seconds later is a coincidence. I happen to have installed the ubuntustudio packages and as for locale:

matthew@Abish:~$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"

Thanks for the additional testing. Based on your experience, I'll simply say that I can't replicate the issue locally, even with en_US.UTF-8 on AMD64. On the other hand, I've not enabled the ubuntustudio repository, which may or may not be related.

I appreciate any help... I know that audacity did not interface with jack at all before; it is nice to see these things shaping together.

It executes normally with qjackctl open (but stopped). If I close audacity, start jack, and run audacity again from a terminal I get:

[theluddite (matt-aggus)]

Exact same problem here. When I run audacity with the jack server run, audacity crashes on startup and crashes jack. I get this:

Any solutions? I'd like to be able to use audacity with jack.

Targeted for 9.04.

[Petr Gladkikh (petrglad)]

This problem affects me too.
My reproduction: 1. start jackctl (that starts jack server); 2. Start audacity; 3. Audacity and jackd crash
Environment: Ubuntu - 9.04 32bit, Audacity - 1.3.7-2ubuntu1, jackd - 0.1160.116.1-3ubuntu3
Console output:

...$ audacity

Correction: my jackd version is 0.116.1-3ubuntu

I also have installed aduacity-dbg package and there is now additional message about failed assertion in console output:

..$ audacity

Seems that pa_jack.c file is from portaudio library. So here are versions of my portaudio library:

libportaudio0 18.1-7.1 Portable audio I/O - shared library
libportaudio2 19+svn20071207-0ubuntu7 Portable audio I/O - shared library

audacity uses it's own patches copy of portaudio.

Can you reproduce the bug with audacity 1.3.9? You can either try Ubuntu 9.10 (karmic) or you grab the package from my backports PPA: https://launchpad.net/~bdrung/+archive/backports

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

I tried to start jackd from command line and it turns out that jackd is still running for a while after audacity is started but continuously reports xruns and then gets killed: "jackd watchdog: timeout - killing jackd".

Console output
$ jackd --verbose --realtime -d alsa >jack-output.txt
no message buffer overruns
server `default' registered
jackd watchdog: timeout - killing jackd

Jackd's output is in attachement.

On Ubuntu Studio 9.04 (32Bit) on an Intel 2x2GHz machine I'm having similar problems (lots of xruns, audacity not coming up), if I start jackd in realtime mode. (As a side note: pulseaudio with module-jack also can't use jack, if jackd is started with the "--realtime" parameter.)

If I start jack like this...

jackd -Z -P89 -dalsa -n4
(nozombies, priority:89, periods:4)

..then Audacity will start and successfully playback through jack.
My parameters don't mean much to this issue here, except that I'm using "-P89" instead of "--realtime".

Another program that I use (Renoise) can connect and playback through jack, even if jackd is started with "--realtime".

[raketenman (sesselastronaut)]

starting audacity with jack already running audacity fails with this message:
audacity: pcm_plug.c:388: snd_pcm_plug_change_channels: Assertion `snd_pcm_format_linear(slv->format)' failed.
Aborted
