Thank you, this works beautifully, just modified v = "88_D0_39_6C_6E_AC" to my version of bluez_card and it works like a charm.

glad you liked it!

It giving me below error
Failed to set card profile to 'headset_head_unit'

this is because that profile does not exist on your headset. perhaps this is an error with your sound system or your headset. Id suggest you turn it off then on again and see if anything changes. If not, then if you're on linux, then you should take a look at pulseaudio and your current bluetooth configs

Thanks, just for reference, use pacmd list-cards when the bluetooth headset is connected to find the value for v
