PipeWire 0.3.77 (2023-08-04)

This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases.

Highlights

Fix a bug in ALSA source where the available number of samples was miscaluclated and resulted in xruns in some cases.
A new L permission was added to make it possible to force a link between nodes even when the nodes can't see each other.
The VBAN module now supports midi send and receive as well.
Many cleanups and small fixes.

it's amazing how rapid the development of pipewire into a "usable state" so that distro quickly put it as drop in replacement for "matured" pulseaudio
- I am shocked that Lennart Poettering, PulseAudio dev, but also Avahi and SystemD dev, whose name might frequently be brought up in conversations about interoperability, reliability, small ego, diplomacy, etc etc, might not be as good at coding an audio stack as legendary C64 demo coder and PipeWire dev Wim Taymans. Shocked, I tell you. Well, not that shocked.
  
  I've read before that Pulse really had a difficult challenge, since it had to really resolve a lot of hardware vendor quirks that essentially would never be resolved. PipeWire gets the advantage of not having those early growing pains, because Pulse went through them. I'm not involved with the development of either to really know one way or another the truth behind that story.
I love pipewire for my audio.
- True, and it's fabulous for video as well.
  
  Ow you are right. I wasn't aware of the video part of Pipewire. Which allows very low latency video recording as well.
Perhaps a shot in the dark, but does anyone know if this update does anything to change the sound issues on Samsung laptops? For example, I have a GalaxyBook3 Pro 360, and it doesn't matter what distro I use; I cannot get audio working. I spent 8 hours one day just going through forums and trying various fixes but could never get anything to work.
- Is it because of missing firmware? From the Arch wiki on ALSA:
  sof-firmware is required for some newer laptop models (mainly since 2019) because they implement their drivers with firmware provided by the Sound Open Firmware project.
  
  I swear I tried all of that and uninstalled the existing firmware, and pulled the newer files. I might give it another go, but I saw on a thread that this is a specific issue with Galaxy Book devices. Someone had a detailed step-by-step guide to get the audio working; I tried it, but it didn't.
- Yeah, it's such a small percentage of users affected too. I have other laptops that run various distros of Linux without issues, but my Galaxy Book can't get any audio unless I plug in speakers or headphones.
  Thank you for the advice.
There's a lot of love for it here, so I guess my experience isn't typical. I updated to Ubuntu Lunar Lobster on my home media machine, which comes with PipeWire by default, and it's utter shit. The vocals and some instruments in my music tracks only play nearly inaudibly from the center channel of my 5.1 surround system. It's unlistenable, even with the center volume boosted.
Seriously, what am I missing? How can it do audio that poorly?
- I've never had a multi-channel setup to experience configuring it, but I am sure there must be guidance out there. In my own experience PW improved my Linux audio experience quite a bit by resolving some issues I had with glitchy audio on my DAC and audio latency that was noticeable in some games.
