Thanks. I created a log from PulseAudio as per given instructions and "fortunately" the issue occured after about 15 minutes. So I started pulseaudio using verbose output to a file, then started listening to some music from spdif, played some youtube videos and some local files, and suddenly all spdif output stopped. I checked and the analog output was working. I *think* that the issue appeared while I was playing a local video, but this may be irrelevant.
I attache the log file. Thanks a lot. ** Attachment added: "PulseAudio verbose log created while the issue with missing spdif output occured." https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/783682/+attachment/2143973/+files/pulseverbose.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/783682 Title: sound stops after a random interval -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
