Słaba jakość dźwięku na Intel ICH6 w Ubuntu 11.04

[byju]

Witam

Mam problem z dźwiękiem w ubuntu 11.04. Dźwięk po prostu trzeszczy jeśli się podgłośni muzukę
na drugim systemie dźwięk jest OK

edit: nie wiem czy jeszcze jakieś dane są potrzebne
Nie wiem czy w dobrym dziale napisałem stąd prośba do modów o przeniesienie w razie czego do innego działu

problem rozwiązał się poprzez ściszenie muzyki (alsamixer) - chyba ze są jakieś inne rozwiązania

[brezniew]

Zasadniczo o to mi chodziło. Bo przy niektórych kartach od jakiejś wartości (zazwyczaj 80-85%) jest już tylko podbijana głośność.

Front Left: Playback 27 [87%] [6.00dB] [on]
Front Right: Playback 27 [87%] [6.00dB] [on]

Twoja karta ponoć dużo lepiej działa pod OSS4 ale to już trochę dłubaniny.

Na początku tamtego tematu jest link do paczki .deb - jej instalacja to wysztko czy trzeba usunąć alse i pulseaudio?

[brezniew]

Raczej trzeba wykonać wszystkie czynności, z tym że to już trochę stary opis, więc pewności nie mam jak to teraz powinno wygladac. Musiałbyś poszukać. Zacznij od tego czy nie ma w repozytorium oss. A Alse trzeba będzie usunąć lub zablokować, wiec to może być więcej zachodu niż to warte. Musisz sam zdecydować czy dźwięk jest na tyle zły żeby się tym bawić.
