@popcornmix, I did as you suggested…
Set “dtparam=audio=on” in config.txt. Previously I had it set to “off” because of an issue that came up with the January update… (January update now iqaudio dac not working?)
…and was expecting the sound to go back to the HDMI instead of “IQaudIO PiDAC +” but it didn’t change.
There is no blacklist.conf file in /etc/modprobe.d so nothing to edit in nano so im assuming that means “snd-bcm2835” wont be blacklisted.
Next I rebooted with logging turned on, opened terminal, started TOP, took a screen shot at time “21:45” before any videos were played… This was the same as before so didn’t feel the need to post it here again unless anyone wants it.
Next I play various videos on my USB hardisk, also fast forward, play, stop, change video, play, fast forward, stop etc. until the occurrence of the sound dropping out again which I can confirm the sound does drop out and the videos freeze again. The video starts playing with no sound after several seconds and if I stop a video it takes several seconds again before returning to the movie selection screen instead of instantly.
I took another screen shot of TOP at time “22:12” similar result as before so no need to upload here unless anyone wants it… “RES” was “96032” at this point.
After this I uploaded the logs. http://paste.osmc.io/idixoworik
