Hi all,
I'm bumping into a very strange issue : setting-up a tunnel between
two devices is OK (thanks to Georg), but only when the configuration
is static (=stored in the /etc/pulse/* configuration files), not when
the same modules are loaded after pulseaudio's start-up. In the second
case, all modules are loaded correctly, BUT the calculated latency of
the tunnel is obviously wrong, for example "current latency:
26695333.53 ms". And no audio can be heard.
The log is full of these :
module-loopback.c: Loopback overall latency is 107.15 ms + 220.18 ms +
13395537.50 ms = 13395864.83 ms
module-loopback.c: Loopback overall latency is 107.34 ms + 0.00 ms +
26188232.17 ms = 26188339.51 ms
module-loopback.c: Loopback overall latency is 106.28 ms + 206.58 ms +
13395547.45 ms = 13395860.31 ms
On my source unit, I have a module-null-sink "default" and a
module-native-protocol-tcp.
On the destination unit, I have the following configuration
load-module module-udev-detect
load-module module-suspend-on-idle
load-module module-cli-protocol-tcp
load-module module-tunnel-source source_name=my-tunnel
server=192.168.100.1 source=default.monitor
load-module module-loopback source=my-tunnel sink=my-alsa-sink
When I start pulseaudio with this configuration, it works. But if I
comment the last two lines and execute them manually using "pacmd", I
get no audio, the messages in the log and the huge latency.
Does anybody know why this happens ? And how to get rid of this (I
need the dynamic behavior) ?
By the way, I'm using pulseaudio 6.0 . Any chance that this would be
fixed in pulseaudio 7.0 ?
Thank you and best regards,
Olivier
Is there some reason why you do not use the default default.pa? I would
at least test it with
a standard setup and clean the modules later. Just to be on the safe
side. When I tested it,
I loaded the modules manually and it worked fine.
There are a few latency issues in module-loopback and I sent a patch set
a while ago which
is addressing them, but I doubt that those patches would help in your
situation. You can try
them however. See
http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/22956
If you have problems downloading I can also send them via mail.
Regards
Georg
