I have recently switched from Ubuntu 12.04 to Debian 8 as support for 12.04 is about to run out. I tried Lubuntu 14.04, Ubuntu Mate 16.04 and Lubuntu 16.04 but couldn't get any of them to run in live mode for any length of time. I have installed Debian 8.6 LXDE and the install went ok and most things work, I have also managed to get Wifi and Bluetooth working but sound has me stumped. Alsamixer opens but shows no sound card. Using terminal I get:
#:~$ aplay --list-devices aplay: device_list:268: no soundcards found...
#:~$ cat /proc/asound/cards --- no soundcards ---
Sound works in OSX and worked in Ubuntu 12.04.
