I am also affected by this latency issue with the loopback module. However, while playing around with pavucontrol I noticed it go away (for the most part, still a slight lag, but seems to be under 10 ms (instead of the 500 ms - 1 s I had before). Unfortunately, the latency issue returned later. Then I stumbled across post #11 of http://ubuntuforums.org/showthread.php?t=1324135page=2. For some reason, if you open up pavucontrol, go to the Recording tab and switch Show to All Streams, then the latency gets much better. Close pavucontrol and it returns. So, whatever pavucontrol does when you switch to monitoring all recording streams should be the answer to this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/566381 Title: Lag when using module-loopback -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Another method, which seems to give even less lag is to *not* load the loopback module, but instead use parec and pacat. e.g. parec --latency-msec=1 | pacat --latency-msec=1 You can probably lengthen these to a few msec. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/566381 Title: Lag when using module-loopback -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just to add, the alsa suggestion of comment 20 is not appearing to work on this laptop (Intel Corporation N10/ICH 7 Family High Definition Audio Controller), and it also is bizarre that you need to specially load the loop-back module from the command line to allow mic mixing in to the audio stream.

Network traffic just for audio shouldn't really be a problem, even really high quality audio is typically 1MB a second. I'm pretty sure your typical network card should handle that just fine, I mean we've done likewise with video on our home network without a problem, high quality mkvs at that.

Same problem here, worked fine back in 9.10, also if you install the other packages (paprefs) and go to SystemPreferencesPulseAudio Preferences and then to the Multicast/RTP tab and enable both the sender and receiver, then check loop audio to local speakers then the audio is not delayed, but is very choppy, chops incessantly, I don't know if this is related to the delay problem using the loopback module, so it might work as a workaround for some people, but is not for me. Audacity offers a playthrough option that works perfectly for me, no delay, no choppiness, except that I have to be recording in order to use it.

[Bug 566381] Re: Lag when using module-loopback
That's an interesting alternate way of doing this. FYI Multicast/RTP is for network shared audio. So your method works by having the computer send an audio stream to it self over the network. The sound is so choppy because an audio stream up and down is to much data for a network card to handle. Even if the sound was not choppy all the new network traffic would still be a problem. -- Lag when using module-loopback https://bugs.launchpad.net/bugs/566381 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
