[pulseaudio-discuss] How can I forward X display but not pulseaudio?

[Boyd Kelly]

Hi Len,

Thanks for this suggestion here.  I also love your forwarded xfce4-panel!!

I did try the jack dbus script below but still not able to start pulse
audio.  However it did occur to me that the 'user-configured' server below
was actually at the source.

[bkelly at zbox ~]$ jackscript.sh
N: [pulseaudio] main.c: User-configured server at
{a31addf0a924b9d66ec2b6a04a91805d}unix:/tmp/pulse-5w2mDtsd3uF2/native,
refusing to start/autospawn.
[bkelly at zbox ~]$

So I simply stopped pulseaudio at the source/local machine before ssh -X
remotehost, and presto! --  I could start pulseaudio, play sound at the
destination while still forwarding the DISPLAY.  Finallly!!!!

It would be nice to know if there is some option/switch/config/method to
control this , without having to shut down pulseaudio on the local machine,
but I'm happy that at least I can accomplish what i need to.

Cheers!

Boyd

# dbus-launch started, DBUS_SESSION_BUS_ADDRESS exported:
export `dbus-launch | grep ADDRESS`

# dbus-launch started, DBUS_SESSION_BUS_PID exported
export `dbus-launch | grep PID`
#jackd -d alsa > ~/Desktop/jack.log 2>&1
/usr/bin/pulseaudio --start

But the result is still:


That user configured server is still the local or source from where I am
using ssh -X.  If I remove the X forwarding then I can still start
pulseaudio. But then I can't forward the display.....  arrrg!
