[X2Go-Dev] parec?

Hi Alex, Mike(?)

I just saw parec running and producing unneeded traffic.

In onmainwindow.cpp:10577ff it says:
QString scmd="PULSE_CLIENTCONFIG=~/.x2go/C-"+
resumingSession.sessionId+
"/.pulse-client.conf "+
"parec 1> /dev/null & sleep 1 && kill %1";

What is the rationale behind this code? As far as I understand it, parec
is supposed to run for one second. I'm not sure that that is what the
code does.

Cheers
Morty

IIRC, Alex and Mihai know more about this.

Hm,

The reason was buggy pulseaudio on windows. If you don't use input
device at several first seconds, input will not work any more. I know,
it is a dirty hack to start parec for 1 sec., but it works. Originally,
this code should be executed only on windows. I don't know which patch
have changed this behaviour. I'll fix it. Thank you for your report, Morty.

regards,
Alex

Hi Morty,

IIRC, Mihai redesigned that part of the codebase, but Alex hasn't
integrated his changes/patches yet. So, my USD 0.02: File a bug, and
add a pointer to Mihai's changes.

Hi Morty,

This code is only executed on Windows, On linux "parecTunnelOk" is
always "false"

Now I have disabled this code for not Windows system at all:

Hm, funny. Okay, with the last commit the code, which starting parec,
will not be even compiled. So it should fix this bug anyway.

Hi Moritz,

I see, that release 4.0.0.4 don't include commit, that should fix this
