When starting ardour using the jack backend, playback only devices
currently do not get displayed. Mixing and Mastering only workspaces
with e.g. a single USB Dac should be a common use case. Take this use
case into account by adding them to the device list. Tested on Linux
with jack-alsa.
This is backwards compatible, quotes are only added if needed.
JACK1 < 0.123.1-30 and JACK2 < 1.9.10-25 fail with either
whitespace or quotes, so nothing is lost.
quotation marks". This patch is incorrect. The string quoting must be done ONLY
when creating a string to be written to ~/.jackdrc or similar, not when
constructing an argument list.
This reverts commit 5626ea2b1f.
A few things need to be tested / completed:-
1) The code is currently guarded by #ifdef COMPILER_MSVC. This is just precautionary. If it builds okay with MinGW ,the guard can be removed.
2) Windows Playback and Capture devices almost always have different names. This needs to get accommodated in our Backend dialog (as in Mixbus)
3) Windows Playback and Capture devices will almost always contain spaces. We need to accommodate this when writing to .jackdrc (surround them in quote marks)
This used to be necessary when we started the JACK server but now that we
write a .jackdrc it only causes problems.
I have fixed this before in some branch, must have been lost in a merge.
Unlike all the other jack backends which allow setting the number of inputs and
outputs with -i & -o, the dummy backend uses -P & -C for this. Make the jackd
command line use these options when the dummy backend is requested with a
specified input or output channel count.
The dummy jackd backend doesn't require a device to be specified, so much
of the error checking in get_jack_command_line_string() is irrelevant, if
not actively wrong, when the dummy backend is specified.
Only perform the checks if the chosen jack backend is not the dummy.
