Bug#926617: plasma-pa: Speakers test doesn't work if libcanberra-pulse is not installed

[Alexander Kernozhitsky <sh200105@mail.ru>]

Package: plasma-pa
Version: 4:5.14.5-1
Severity: normal

The speakers test functionality in the settings of the plasmoid didn't work for
me. When I tried to use it, I saw the following in the console:

ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM 2
ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM 2
ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM 2

After studying the code, I noticed that test sounds are being played with
libcanberra, and the device ID is backend-specific there. It seems that the
numeric IDs are used by Pulseaudio backend, not ALSA.

So, I installed the Pulseaudio backend:

$ sudo apt install libcanberra-pulse

This fixed the bug for me.

So, please add libcanberra-pulse to Recommends of plasma-pa.
