0.7.9 Linux release from ayufan

[dukla2000]

There is sound here (Vestel 22L1333G TV/monitor, LXDE image), but it plays back several times faster than it should, i.e. at a much higher sample rate. (The www.audiocheck.net site contains a lot of interesting sounds that I used to test this.)

This is a known issue with pulseaudio with the 4.4.132-1075 kernel that is default in the 0.7.9 Ayufan release.

You can check your kernel version with
uname -a

You can upgrade your kernel with
sudo apt-get update
sudo apt-get install linux-image-4.4.132-1083-rockchip-ayufan-gfd3f12ca5fae
and reboot
