alsactl: save_state:1497: No soundcards found…
Fala galera, primeiro peço desculpa pela falta de atualizações, mas tá faltando é tempo mesmo. =/
nesses dias que se passaram aproveitei para atualizar o kernel do meu gentoo para o 2.6.24-r2, tudo normal menos o som que parou de funcionar!
/etc/init.d/alsasound restart
