This PC has been on Ubuntu for ~10 years. It has never been plain sailing but had been working until 2 days ago when we left a DVD video on pause in VLC. When we unpaused a few hours later, the audio started stuttering constantly at high volume that can't be lowered in either VLC or the OS once it starts.
The DVD video/image playback looks ok. Playback of .mp4 files in VLC is okay (so a potential workround is to rip the DVDs). Audio works fine in Firefox, Steam games etc - so I believe the problem is isolated to vlc dvd playback.
The dvds it has happened to so far reputedly have some copy protection or encryption on them. I suppose scrambling the sound might be a feature of that.
The soundcard is onboard: HDA Intel Playback is IEC958 / SPDIF digital stereo, which goes to an AV Receiver, which is currently set to split the stereo signal into virtual 5.1 surround sound. If I buy an adaptor there would exist the option to play sound via the graphics card and use HDMI instead.
The audio is set to Pulseaudio Sound Server. Switching it to ALSA doesn't seem to affect this problem.
vlc is giving numerous error messages (pasted below), most of which I've searched and the results haven't seemed particularly useful so far.
At the moment I think it might be a problem with the buffer size or that too many other programs are open relative to the buffer. So I'm looking at vlc Advanced Preferences > Input/Codecs. But if anyone has seen the same errors I'd be hugely grateful for any pointers.
This block of errors reflects multiple attempts
