hagbard renamed this task from module pcspkr missiing to module pcspkr missing.Jan 26 2019, 6:35 PM
hagbard updated the task description. (Show Details)
syncer edited projects, added VyOS 1.3 Equuleus; removed VyOS 1.2 Crux.

This is no longer compiled as a module but rather statically into the kernel (

  • /sys/bus/platform/devices/pcspkr
  • /sys/devices/platform/pcspkr

What exactly do you mean my "capabilities missing"`

As far as I recall it doesn't initializes is correctly anymore, you can test with beep. The system beep you can set via cli is broken since then.

c-po changed the task status from Open to In progress.Aug 29 2020, 7:22 AM
c-po claimed this task.
c-po set Is it a breaking change? to Unspecified (possibly destroys the router).

echo -ne "\a" should give you a beep sound on the the system speaker too, if you just want to quickly test it. I tested it with deb10 minimal install, works via qemu too.
e.g: qemu-system-x86_64 -smp cpus=3 -soundhw pcspk -m 1024 -enable-kvm -drive file=os.img,media=disk (os disk is a deb10 netinstall).
With capabilities I meant the listed capabilities listed under the input link via sys:

ls /sys/devices/platform/pcspkr/input/input19/capabilities/
abs  ev  ff  key  led  msc  rel  snd  sw

They are missing as well as the input link (subsys input), bustype and verdor id and version are usually under input too.

Also beep uses /dev/input/by-path/platform-pcspkr-event-spkr and doesn't care about /sys.

@c-po will fix it, but I used .142 while the conifg file was from 136, so please review first. I tested it and the system speaker is fully functional again.
You can test it quickly via `echo -ne "\a"', which should make noise. Beep seems to be broken, looks like it can't be used via sudo, something I may can have a look later into.
