Thank you for your reply, I added the necessary information to the bug
Sorry for assigning it to the ubuntu-audio team, I had no idea it
wouldn’t be appreciated. Filing the bug against phonon was my first
guess too because that would be KDE-specific, but the bug triagers for
Phonon don’t seem to be active because no one responded for weeks.
You quote Mackenzie in your e-mail, but I haven’t seen the reply of that
person on the mailing list here? And how would I investigate which
applications are polling the device via alsa-lib?
