I do run Manjaro Linux, and I do need to type cont twice to make Ardour start in GDB.
Where does gdb break so that you need to continue? Could you post the output? That would be helpful.
Sure!

See above: Request for help testing before 6.7 release - #8 by x42
echo "handle SIG32 noprint nostop" >> ~/.gdbrc
I’ve tested and provided the example output after doing this - for some reason it didn’t make any difference. Should I logout/log-in or reboot for it to take effect?
$ cat ~/.gdbrc
handle SIG32 noprint nostopDoes executing handle SIG32 noprint nostop on the gdb commandline before run help?
Is this thread the best place for positive feedback? I’ve just downloaded and tried this nightly version
Ardour-6.6.489-dbg-x86_64-gcc5
running on Ubuntu 21.04 and it’s working perfectly as far as I can see, other than the DSP load being at around 50-55% instead of 30% which I’m going to assume is because it’s a debug build. Running this optimised nightly:
Ardour-6.6.493-x86_64-gcc5
and the DSP is back to 30% or so. This is mostly because I have a convolution reverb and a long IR which sucks up CPU. Let me know if you need any more details about the system but as far as I can see, it’s all working fine for me

That’s good to hear.
We’re mostly interested that it works for you.
Every user has a different workflow and uses a different subset of Ardour’s features.
Fedora mock build for rpm from git (rev 6.6-493-ga01377f168), Intel 64-bit) okay with just a few minor tweaks.
Installed and used it a couple of times and noticed some nice improvements, but no problems.
Great job!
Yes is does! Not sure why the .gdbrc file isn’t having an effect then.
I noticed that with Linux/ALSA I can use an USB audio interface (e.g. Zoom H2n) for input, the system soundcard for output, and Zoom R24 as Mackie control surface. Simultaneously. Wow, I didn’t know that was possible…
That was a new feature in 6.0. It is also possible to use more than 2 devices, but there is no GUI for it yet.
One can specify more additional device using the “ARDOUR_ALSA_EXT” environment variable, semicolon separated with optional additional parameters such as sample-rate and buffersize if they differ from the main settings. e.g.
ARDOUR_ALSA_EXT="hw:2@48000/512*3;hw:3@44100" Ardour6
PS. If you only use 2 devices, the output (playback device) is resampled. This is so that recording quality is not affected.

Please forgive me if the question is not welcome, and if it is I will delete it.
Is there any roadmap for version 7.0 or will you start thinking about it after 6.7 release?
Mostly stuff that didn’t happen from 5.x → 6.0 and was postponed to 7.0
For the sake of my understanding…
“aplay -l” lists H2n as card 1 and R24 as card 2.
ARDOUR_ALSA_EXT=“hw:2@44100;hw:1@44100”
This makes both devices available, but in1 and in2 are the H2n ports, in3 … in10 are the R24 ports. The order of the devices in ARDOUR_ALSA_EXT does not matter?
Also, the (input) device chosen in the Audio/MIDI setup, does it matter?
Not sure if this has been reported by others. split/separate isn’t working for me in a project. On latest nightly.
Eeek!
Please tell me this isn’t in 6.7… 
Edit point is set to “marker” and there’s no marker crossing the selected regions.
Oo that was an easy fix, thanks! Is marker the default setting because I don’t remember ever playing with that control.
