Nezvučící aplikace [vyřešeno]

[Jafff]

Tak jo. Dělám to nerad, ale musím vás taky otravovat s dotazem.
Souhrou nešťastné náhody, mé nezkušenosti a notné dávky blbosti jsem si rozhasil zvuk. Současný stav je ten, že ani u jednoho videa, mp3 nebo podobného souboru mi zvuk nejede (ať už v Totemu či vlc), kdežto například video  z youtube přehraju bez problémů i se zvukem. Je mi jasné, že jsem smazal něco, co jsem smazat neměl, protože v Totemu se mi znefunkčnilo tlačítko ovládající hlasitost - je prostě šedivé a nejde s ním nic dělat. Kdybyste mi tedy mohli poradit, co s tím - co reinstalovat, jestli radši nepřemazat celý systém a tak podobně.
Jako další vodítko mohu poskytnout tohle - v nastavení zvuku mi po zmáčknutí tlačítka "test" vyskočí následující hláška:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect: Connection refused

Zkuste si hrát s příkazem:

alsamixer

potom pošlete výpisy příkazů:

lshw
cat /etc/modprobe.d/alsa-base
cat /etc/modprobe.d/blacklist

[Jafff]

alsamixer vyvolal jen podivně neaktivní aplikaci (žádné barevné sloupce, prostě nic), příkazy dělají toto:

Tak tohle už není třeba řešit. Jelikož jsem měl systém jenom dva dny, radši jsem ho rovnou reinstaloval. Zabralo to řádově míň času, než řešení spouště, kterou jsem nadělal. Každopádně díky.
