    Default A way to track changes in the system (Alsa)?

    Error when launch gvolwheel (application which lets you control the audio volume):
    cannot open mixer device
    Then launch volti (another application for controlling audio volume), all Ok.
    Close volti, and again launch gvolwheel - successful! But after reboot again this same error..

    strace output does not help me..

    It reads to me that some app has seized the audio device upon boot where gvolwheel can not access the device as another is using it. For some reason volti is able to seize the device away for use. And then when you close volti it properly closes its access to the device, leaving it open for another device to use, which in the case of your efforts is gvolwheel.

    Are you using pulseaudio ? I suspect not , but my suspicions could be wrong.

    oldcpu, that's right, I don't want to use pulseaudio.
    But:
    1. the same thing happens and after launch Yast2 sound > set Card 0 as default,
    2. other applications, e. g. alsamixer, works without problems.

    That's why I want to understand what changed, but don't want to read tons of manuals

    Note: I used notorious Suse Studio to build this system, and now have such strange problems
