I also tried the gui route - that failed totally as no devices ever
displayed.
What you do need is a asound.conf file in /etc Mine has the following
content (you can ignore the device names, but you should get the idea:
Code:
--------------------
pcm.!default {
type plug
slave.pcm "hw:0,0"
}
ctl.dmixer {
type hw
card 0
}
pcm.BOOM {
type plug
slave {
pcm {
type bluetooth
device macaddress
profile "auto"
}
}
hint {
show on
description "Bluetooth BOOM audio output device"
}
}
ctl.BOOM {
type bluetooth
}
pcm.WAVE {
type plug
slave {
pcm {
type bluetooth
device mac-address
profile "auto"
}
}
hint {
show on
description "Bluetooth WAVE audio output device"
}
}
ctl.WAVE {
type bluetooth
}
pcm.TEST {
type plug
slave {
pcm {
type bluetooth
device mac-address
profile "auto"
}
}
hint {
show on
description "Bluetooth TEST audio output device"
}
}
ctl.TEST {
type bluetooth
}
--------------------
Touch - Muse M50 EX TPA3123 T-Amp Mini - Acoustics Q10 speakers
