V tom logu mplayeru je jasně napsáno, že zařízení /dev/snd/pcmC0D0p je busy, tedy již používané jiným procesem. Detaily zjistíš příkazem

sudo lsof /dev/snd/*

Nejpravděpodobněji to bude používané pulseaudiem.

[HrabalVojta]

pulse audio jsem odstranil kompletně ...

Takže to má obsazený amarok a knotify4.

Hlavní problém je řádek v mplayeru:

Failed to initialize audio driver 'alsa:noblock:device=hw=0.0'

Zřejmě máš v konfigu mplayeru natvrdo nastavé zařízení alsy hw=0.0. To je přímo raw zvukovka a obchází to dmix, který se při odinstalovaném pulseaudiu defaultně používá pro zařízení "default". Přes dmix jede zřejmě ten amarok, ale ten mplayer přistupuje přímo na hw:0. Zkus mplayer spustit s parametrem:

-ao alsa:noblock:device=default

Pak by ten amarok neměl vadit.

Jak píše mplayer, máš to hw:0,0 pořád obsazené. To vyřeš jako první, ať to používá dmix (tedy zařízení default) a ne napřímo.
