Ok, I have Bose 5 Companion usb-speakers and just installed fresh opensuse 12.1. with KDE and cant get the sounds work. However I can hear test sound, on page yast->sound->other. On that page I tried to use this “bose usb audio” as primary sound source, but then I dont hear even the test sound. (Other sound sources i have “intel corporation” and “nvidia corporaton”.)
Could somebody help me please to configure sounds properly?
Please check in System Settings > Hardware > Multimedia > Phonon
There are lots of settings here. But basically you need to make sure your Bose device is the preferred device in the ‘Device Preference’ section
*FYI: This section is a little buggy. Even if you don’t change anything it asks you to save the changes and sometimes the kde crash handler comes up when you exit.
Right click kmix > Select Master Channel
Select the radio button for Bose device
Also normal click > Mixer >
Make sure your playback device for Bose > Volume is around 80% and not muted
To help configuring, also install the application pulse audio volume control (pavucontrol) and use that to help you tune pulse audio for individual applications. I blogged a bit about this here: Pulseaudio Basics for openSUSE with pavucontrol - Blogs - openSUSE Forums
