Following comments by @aatchison last week that there was a known issue with the analogue audio output ( i.e. the headphone jack in the rpi board ) and
rpi cmd aplay hanging after a number of “plays”, i’ve been looking at speaker alternatives.
Today I tried a “USB 3D 5.1 Sound Card” with a Rpi3
Previously I had added a PS3 Eye camera and a wireless keyboard are usb accessories, running official pi3 power supply,
The combination of the both of them on the power supply of the Rpi meant that only one would function.
That is only the Sound Card would work.
So I have had to a powered usb hub to run the PS3 Eye camera on the powered hub. Something similar to:
Rebooted and the Mycroft server has been running fine with no Audio hangs
and a “hey mycroft what time is it” completes in about a couple of seconds.
