Thank you for that tip to get sdl pcm working. It is as follows:

As root, edit /usr/share/alsa/alsa.conf and replace both occurrences of "pcm3" by "pcm2".

The only other problem i've found so far is that my Thinkoutside Stowaway BT keyboard refuses to pair with it.

I open control panel -> bluetooth

I select "New". "Select a device" panel comes up.

I hold down CTRL-FN-FN a couple of seconds and it finds Think Outside Keyboard.

I click on the think Outside Keyboard item in the 'Select a device' list

"Pair with device" menu comes up and gives a code to enter, and trusted device is checked

I click OK

'Pairing' status window comes up.

I enter the 4-Digit code number and wait: in various tries I get either an error "Pairing failed. Device resources exceeded. Try again? or Authentication failed.

(edit) just tried it again and found i have to hit the Enter (Return) key after entering the code number. Sheesh PBCAK

The UI is so much slicker. From an audio designer standpoint the clicking sound when you touch the screen is a sharp sound like hitting a nice hard crystal, instead of a piece of cardboard. Funny how these associations colour the feel of the device. Also the dark theme is way cool. Loving it
