I’m having the “no sound” troubles using OSMC with RPi 2.
The HW setup is quite simple, the Pi is connected directly to a projector with built-in speaker using an HDMI cable. The Pi is running a fresh installation of OSMC & Rapsbian (installed using NOOBS). I tried using the OSMC image and it doesn’t make any difference though.
The problem is that I can’t get any sound out of the projector unless I physically reconnect the HDMI cable after OSMC is loaded. Rebooting the Pi (no matter whether it’s over SSH, from the GUI or by physically unplugging the power cable) means I need to do the procedure again.
I tried a lot of the general guidelines (e.g. http://elinux.org/R-Pi_Troubleshooting#Sound_does_not_work_with_an_HDMI_monitor), neither of which worked. I also experienced this problem with OpenELEC (v. 6+, v. 5 worked fine). On the other hand, Raspbian has worked and still works fine.
The included logs show the boot process, opening a YouTube video (no sound), stopping the video, unplugging and reconnecting the HDMI cable and playing another YouTube video (sound working fine). The logs can be found here : http://paste.osmc.io/siyugopoti.
Any thoughts on how I could get the sound working right away?
