I have been successfully using the command

aplay -D bluealsa:HCI=hci0,DEV=EB:06:BF:19:C2:D3,PROFILE=a2dp Open.wav

to play sound over a BlueTooth device.

HOWEVER after a few hours of trouble free operation, I suddenly started getting the following error message:

Playing WAVE 'Open.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set_params:1363: Unable to install hw params:

If I reboot the R-pi, this goes awy and all is OK again.

What is going wrong and how cn I fix it without rebooting?
