Sergey,

Thanks for this help. Running `$(guix build pipewire)` returned the same path 
shown in your example, so I tried simply copy-pasting your example to 
~/.config/alsa/asoundrc and restarting my system

Sound did not work, but messages in the qutebrowser process output were 
slightly different. foreign text translates as: "host dropped",
```
[1588:1588:0117/013614.549773:ERROR:alsa_util.cc(204)] PcmOpen: 
default,ホストが落ちています
[1588:1588:0117/013614.559451:ERROR:alsa_util.cc(204)] PcmOpen:

[1588:1588:0117/013614.575316:ERROR:alsa_util.cc(204)] PcmOpen:

[1588:1588:0117/013614.588043:ERROR:alsa_util.cc(204)] PcmOpen: 
plug:default,ホストが落ちています
```

These messages differ from the earlier messages that basically said "file not 
found".

Thanks for helping me. I will sleep now and maybe try more things tomorrow,
