Niska jakość dźwięku, Fedora.

[celon]

Witam, od 3 dni mam zainstalowaną Fedore 17.

Programy: Rhythmbox / XMMS

Sprzęt: Zintegrowana karta dzwiekowa "HDA ATI SD"

Problem: Niska jakość dźwięku, "charczenie". Probowalem wszystko mieszac w ALSA ale na nic pozytywnego to sie nie zdalo.

Bardzo zalezy mi na uzywaniu Rhythmbox gdyz jest odrazu wbudowany w system, wygodny dla mnie i posiada opcje zalogowania na last.fm. W miare mozliwosci chcialbym by obylo sie bez instalacji dodatkowego odtwarzacza lecz jesli uwazacie, ze jakiś konkretny pomoze to zainstaluje go.

Pozdrawiam.

Odtwórz programem mplayer plik mp3, ogg lub inny audio z linii poleceń
w terminalu i sprawdź jakie próbkowanie wyświetli mplayer w końcowych wierszach
podczas odtwarzania .
Chodzi mi o taki wiersz jak w tym przykładzie:
"AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample)"

Odtworzenie pliku audio programem mplayer:
mplayer -ao alsa plik.mp3
Jeśli używasz pulseaudio to sprawdź w ten sposób:
mplayer] -ao pulse  plik.mp3
