current vanilla Pd (debian package) is freezing (tested on Linux Mint) when Jack is used and the number of channels are changed.
You seem to have CSS turned off.
Please don't fill out this field.
i think this only happens if you started jack implicitely via Pd. if jack was running before Pd is started, that shouldn't happen.
could you confirm?
No, Jack Server was running before Pd was started.
pelase provide detailed steps to reproduce the problem.
the following works for me:
- start jack (i start it via qjackctl)
- start "pd -jack -channels 2" ("pure_data_0" appears in qjackctl connection-list with 2 ins and 2 outs)
- in Pd go to "Media -> Preferences -> Audio..." and select 12 input channels and 7 ouput channels
- click on "OK" (qjackctl is updated accordingly, "pure_data_0" now has 7 outputs and 12 inputs)
i noticed a possibly related problem (with both vanilla 0.43 & 0.44) when using jack either without input or without output channels.
the following will output audio I/O stick...closing audio:
$ pd -jack -noadc -outchannels 2
if i simply start pd with multiple channels (e.g. pd -jack -channels 4) and then go to Media->Audiosettings to change the number of input (or output) channels to 0, the audio dialog closes, the console starts printing watchdog: signaling pd... and Pd does not react any more
pd -jack -channels 4
I can't recreate the original bug but found and hopefully fixed the problem
with in-channels equal to zero.
