PipeWire 0.3.68 Released With New RTP Session Module, Many Other Changes

https://www.phoronix.com/news/PipeWire-0.3.68

PipeWire 0.3.68 is out today as a significant update for this alternative to JACK and PulseAudio as well as managing both audio and video streams on the Linux desktop.

First of all with PipeWire 0.3.68, symbolic links are now used to the pipewire binary rather than recompiling the same binary multiple times.

There is also a new RTP session module that leverages the Apple MIDI protocol for low-latency bi-directional MIDI between systems while Opus encoding was added to the RTP formats. Also notable with PipeWire 0.3.68 is a number of FreeBSD compilation fixes for improving the FreeBSD build support.

The existing pulse-tunnel module has seen improved rate matching and synchronization, the RAOP sink was ported to new OpenSSL functions, and the ACP code was updated with new PulseAudio UCM code. Upstream PulseAudio meanwhile has disabled upmixing by default while shipping configuration files that distributions can install to enable upmixing support.

PipeWire 0.3.68 also has a variety of different fixes like avoiding a crash in some cases when a Bluetooth device is disconnected.

Downloads and more details on the many PipeWire 0.3.68 changes via the FreeDesktop.org GitLab.

Code: Select all

The ALSA plugin has experimental support for IRQ based scheduling. This
should decrease latency for some (mostly USB) drivers. This should bring
latency within JACK latency. More work on this will be done before the
1.0 release later this year

It looks like I will be avoiding Pipewire altogether until at least the 1.0 release. If it cannot provide low latency audio via ALSA and a USB device, it is of no use to me. Latency via ALSA should be at least as good as with JACK, not worse. This feels like the early days of Pulseaudio all over again, an extra hurdle towards achieving low latency audio.

I am pleasantly surprised to see, that Pipewire is the default sound server in Ubuntu Studio 23.04 Beta. And it seems to work pretty decently.

Anyone having problems with .68? I'm on Ubuntu, Reaper, constant crashing since upgrading. Rock solid on .66

Running reaper from the terminal gives no clues, just segfault.

Can you at least please try 0.3.69 before reporting the bug to the issue tracker?
