When I wake headset, I'm getting no audio. Volume slider works but no output.
The only ways to remedy this is to restart headset or plug in headphones.
Likewise, if I wake headset with headphones already plugged in I get the same problem and have to remove headphones to get audio.
Seems to be a problem since latest firmware. I've done a factory reset but the problem remains.
I think I've noticed this problem with my Q1 if I put it in sleep mode for too long. Like you said, the fix is to do a restart. Except for very short periods of time I do not use sleep mode. I fully power down my Q1 between sessions. I have never noticed any audio problems starting up from fully powered down.
