Dotaz: nVidia Corporation MCP55 High Definition Audio - nefunguje mikrofon

[Jaroslav]

Zdravim, mam problem s integrovanou zvukovou kartou (nVidia Corporation MCP55 High Definition Audio) na doske ASUS M2N32 a to taky, ze nefunguje mikrofon - ak nieco do mikrofonu hovorim, v sluchatkach sa pocujem, ale ziadny program to nezaznamena, nefunguje "recording". V alsamixeri je vsetko v poriadku, unmutnute a na maximalnu hlasitost, tam som pozeral najprv a odvtedy uz vela krat. Google sice nasiel rovnaky problem a to iste aj tu, riesenie som tam vsak nenasiel. Neviete ako by som mohol ten mikrofon spojazdnit? Distro Archlinux, up-to-date.

Zkus si nainstalovat gnome-volume-control a v nem povolit nahravani z mikrofonu.

[Jaroslav]

Taky balicek v Archlinuxe nemam a navyse bezim na KDE...

Přepnout capture vstup na mikrofon, zapnout nahrávání a pohrát si se vstupní hlasitostí (momentálně 0, může být jako zesílení nebo zeslabení). Ovládání alsamixeru viz man alsamixer, doporučuji pro přepínání capture vstupů (mezerník a podobné "vychytávky").

[Jaroslav]

thx, v alsamixeri som mal vsetko naplno a switche ktore mali tuto moznost prepnute na "mic" a to ma poplietlo. Riesenie bolo medzernikom prepnut capture.

[dustin]

Jojo, alsamixer má poněkud sverázné ovládání. Hlavně že už to šlape.
