[Alsa-user] app says: "ALSA error: cannot open audio device"

[Dexter F. <Dex...@gm...>]

Got a guitar tuner app here called tuneroid from kde-apps.org.

When launching it says "ALSA error: cannot open audio device"

Why? 

here's my ~/.asoundrc

pcm.SoundBlasterLive!_0_asym{
        type asym
        playback.pcm SoundBlasterLive!_0_dmix
        capture.pcm SoundBlasterLive!_0_dsnoop
}

pcm.SoundBlasterLive!_0_dmix {
        type dmix
