Hi,
I want to capture the audio stream of my TV with my PCI-E Toslink sound
card and play it back on my usb XLR soundcard. The reason why I do that
is to use my own music boxes rather than the TV speakers. With toslink +
XLR I do not have problems with ground loops etc.
I am using the pulseaudio loopback module with its default
configuration. The problem is, that the delay between picture and sound
is about one second off, and the longer I wait, the more delay it gets
(30 seconds and more). It is no usable like this.
I tried to play with the latencies of source, sink and the tv delay
itself without sucess. I also tried streaming with pacat directly as
described here:
https://thelinuxexperiment.com/fix-pulseaudio-loopback-delay/
I also tried to change different parameters of the loopback module or
the sources/sinks, but that did not help. I never changed any global
pulseaudio config to avoid larger configuration issues. The CPU usage of
pulseaudio is at 3% with the loopback module
Can anyone help me to get rid of this lag?
Hi Nico,
which version of PA are you using? Can you provide logs?
Regards
Georg
