From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I am running into a bug with pipewire where every time my laptop wakes from sleep, my audio devices (both input and output) get duplicated. So if I close my laptop lid and open it 5 times, I will have 5 sets of speakers and 5 microphones. And at that point, the volume controls stop working and everything kinda goes to shit. If I restart the pipewire service, everything starts working fine again.

The workaround I am using is I made a systemd service that restarts the pipewire service each time the device wakes from sleep. And that works fine. But I was wondering if anyone else ran into this and if there is a better solution available.

Which version are you currently on? I thought this was in 0.3.77 and fixed in 0.3.78

Oh. I just checked. I'm on 0.3.79, and yes it's fixed. I just had to disable my service to check. Thanks for the heads up!

This is the best summary I could come up with:

Red Hat multimedia expert Wim Taymans has released PipeWire 0.3.80 as the newest version of this open-source solution for efficiently handling video and audio streams on the Linux desktop.

With PipeWire 0.3.80 its Vulkan SPA plug-in has added DMA-BUF support for efficient handling of buffers.

The work is part of this merge request that had been open for six months on introducing Vulkan modifiers support for this PipeWire plug-in to enable DMA-BUF usage.

A set of 22 patches made up this change authored by the wlroots developers.

PipeWire 0.3.80 also adds a new "Tag" parameter to allow for arbitrary metadata to be transported out-of-band in the graph.

PipeWire's echo cancelling code was also ported over to the WebRTC audio processing code, a regression in locating monitor sources by ID were fixed in the PulseAudio server code, and updates to avoid potential crashes.
