Some additional diagnostics

alsa speaker test for all 8 channels, when sent direct to the USBStreamer works fine

Code:

speaker-test -Ddefault:USBStreamer -c8  

speaker-test 1.1.8

Playback device is default:USBStreamer
Stream parameters are 48000Hz, S16_LE, 8 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 2048 to 16384
Period size range from 1024 to 1024
Using max buffer size 16384
Periods = 4
was set period_size = 1024
was set buffer_size = 16384
0 - Front Left

But the same when sent to the camilladsp alsa pipe gives the following error

Code:

speaker-test -Dcamilladsp -c2

speaker-test 1.1.8
