[solved] Problem with OSSv4 and Pragha/Consonance

Hi all,

I am getting some problems having Pragha/Consonance work with oss:

$ pragha -a oss -g /dev/dsp -m /dev/mixer

ao_oss ERROR: Unrecognized channel name "samplerate INT" in channel matrix "samplerate INT"
ao_oss WARNING: Input channel matrix invalid; ignoring.
ao_oss ERROR: cannot set rate to 44100

(pragha:17893): pragha-CRITICAL **: Unable to open audio device

(pragha:17893): pragha-CRITICAL **: Audio init failed, choose appropriate settings from the preferences.

Found a fix:

sudo vmixctl rate /dev/dsp 44100
