Hello, I'm a good sound fanatic ! That's why I disabled pulseaudio, in order to avoid any resampling process on my music. I restarted my computer, and now, in the Multimedia Module of systemsettings, there is no any device listed (but "default") in Phonon. So, I can't set any device as default :(. I tried to check the "show advanced devices", but nothing more appeared. In the past I did the same thing successfully. When I removed Pulseaudio, phonon listed all alsa devices, and I could choose one and the play music. Reproducible: Always Steps to Reproduce: 1. Disable or remove Pulseaudio 2. restart Computer 3. Phonon doesn't list any alsa device Actual Results: I can't select a sound device when I remove or disable pulseaudio. Expected Results: 1. Disable or remove Pulseaudio 2. restart Computer 3. Phonon should now list all alsa devices, instead of pulseaudio server I tried DeadBeef (music player). We can choose the sound device in the player. All alsa devices are listed in this app. So, I think Alsa is fine, but phonon ha a problem to list its devices.
You have to make sure the gstreamer-alsa respectively the vlc-alsa plugins are installed depending on which phonon backend you use.
Thank you for your answer. I'm using gstreamer engine, on a fresh install of Kubuntu 16.04, so I have : - phonon-backend-gstreamer (was already installed) - gstreamer-alsa ( was not installed. so I installed it). After restarting, the problem is still present ! I can't have any device listed when pulseaudio is disabled. As I said on #kde IRC channel, it worked in the past. The might be a bug somewhere now !
