What happened?
Setup:
Raspberry Pi3
USB Sound card
Had a working setup (with a raspotify version from begin of 2023 (do not know which one unfortunately)) and did a "apt full-upgrade".
Suddenly there was no spotify sound anymore.
speaker-test -c 2 gives the pink noise on both speakers
during "playback" librespot -d ? shows:
ALSA lib pcm_dmix.c:1038:(snd_pcm_dmix_open) unable to create IPC semaphore
changing the alsa.conf from
defaults.pcm.ipc_perm 0660
to
defaults.pcm.ipc_perm 0666
avoids the error, but it's not playing anyways.
without playback librespot -d ? shows:
`[2023-08-28T10:56:05Z INFO librespot] librespot 0.4.2 a6e1258 (Built on 2023-06-21, Build ID: zuwVQKTQ, Profile: release)

The librespot log shows the songs and that it's playing through alsasink.
Tried also another USB sound card without success...
Please help, thanks!

Ways to reproduce (used Raspberry Pi3 Model B+):
Flash latest (bullseye) RaspberryOS lite 32bit on SD Card
add these lines to config.txt:
gpu_mem=16
dtparam=audio=off
boot
sudo apt update
sudo apt full-upgrade
sudo nano /usr/share/alsa/alsa.conf
set:
defaults.ctl.card 1
defaults.pcm.card 1
sudo apt-get -y install curl && curl -sL https://dtcooper.github.io/raspotify/install.sh | sh
result: no sound
after reboot: no sound
after connecting with spotify (before see first post):
librespot -d ?
ALSA lib pcm_dmix.c:1038:(snd_pcm_dmix_open) unable to create IPC semaphore
after fresh boot
speaker-test -c 2
works fine and you hear pink noise
Please help...
ok, have the solution: my sound card suddenly stops supporting 44,1kHz (new driver with update?) so I had to set:
LIBRESPOT_SAMPLE_RATE="48kHz"
LIBRESPOT_INTERPOLATION_QUALITY="High"
and now everything works well again!
and now everything works well again!
Thanks for this - it also resolved the problem for me on a Pi Zero 2W which exhibited exactly the same symptoms as you. I have a similar setup with a USB DAC (Topping TP30). Hopefully helps others find via google...
