2 months ago Thanks for the post. There are a few things. It would be helpful if you could post the results from
$ shairport-sync --displayConfigSecondly, what sound server is being used -- is it PipeWire or PulseAudio?

I am using jack rodeo backend (I think), custom compiledThanks. And what about the sound server in the Pi? If it has a GUI, it has a sound server...

2 months ago hmm... good point! I guess you are talking about alsa 😅 so maybe the 44.1 to 48kHz conversion could be causing this?

}Thanks. What I'm trying to discover is whether PipeWire or PulseAudio are running. If they are, they can interfere with Shairport Sync.
To see if PulseAudio is running, enter:
$ pactand if it's not installed, we can reasonably conclude that PulseAudio is not running. If something comes back, please post it here.
To see if PipeWire is running, enter:
$ pw-monand again, if it generates a response, please post it here...

2 months ago Yeah... I mean I want to... but this jack setup was a few years to learn / build.
I have audio input on that DAC and librespot setup in jack ... and I am happy it works. I have no clue if I am proficient enough to switch to PipeWire. I think I tried it once... but since I am not using it I guess I have failed 🤪

2 months ago Just thinking about this -- Shairport Sync's PipeWire backend was completely rebuilt some time ago and it pretty good now, and really pretty easy to use. I guess -- but don't know -- that Librespot's use of the Jack interface is bridged into PipeWire anyway.
Overall, therefore, it might not be too hard to experiment with using Shairport Sync's PipeWire backend without disturbing the Librespot setup. (Note that Shairport Sync's PipeWire backend is pw. It is not pipe, which is for a standard Unix pipe output.)

2 months ago Yes, ... I will do a fresh system soon. This linux is completely misconfigured ... also ARM (RT ... for realtime) kernel etc. pp. ... built around low latency in JACK. There are a few threads about PW in the forum from  blokas labs / for pisound ... where nobody helped them .. so I figured it's work of a few days / weeks when I try it as well. I will definitely... thanks for coming back / rhinking about this!Am 04.08.2024 um 13:27 schrieb Mike Brady @.***>: Just thinking about this -- Shairport Sync's PipeWire backend was completely rebuilt some time ago and it pretty good now, and really pretty easy to use.

2 months ago removed 'audio_backend_buffer_desired_length_in_seconds' from my config and now it's gone! huray!
What happened?
Everytime a new connection is made the first bits come in chopped ... it stutters. I kinda always had this... but now I successively tried all out options (I had soxr best for a long time ... and dialed that down to fast and now tried basic instead of soxr). Anyhow... all options I tried show this phenomenon.
Can I try something else? Maybe I'm searching in the wrong spot?
Relevant log output
System Information.
Rpi 5 + Bookworm 6.1.0 aarch64 with jack2 + pisound DAC + nvme SSD
Configuration Information.
PulseAudio or PipeWire installed?
How did you install Shairport Sync?
