I have a rasperry pi 2B with a hifiberry digi. Additionally I have a waveshare 5 inch lcd(b) touchscreen connected via hdmi and usb for touch controls + another usb with seperate power supply. However, the documentation of this displays installation is fairly poor. So I installed their preconfigured image (jessie) and did your installation steps, which made the taskbar flicker and the gui unusable.
Installing your preconfigured image and runnig the installation script of the display causes that there is no working audio device detected, even if I go through you installation steps again. Navigationg to Audio settings in gui is prompting:
"Gstreamer was unable to detect any sound devices. Some sound sound system specific Gstreamer packages may be missing. It may also be a permissions problem"
The hifiberry works fine just installing your image without installing the display. Any idea on this? Thanks in advance!
