Hallo,
ich habe ein Samsung Bluetooth headset, dies ist leider extrem leise. (ich bin leise)

Gibt es eine App mit der ich meine Lautstärke zu verstärken,?

Freundliche Grüße

ich glaube das ist nur mit gerooteten Phones möglich.

edit: ich meine, mal bei den XDAs gelesen zu haben, dass man hierfür die default_gain.conf bearbeiten muss.

Hallo,
Im genannten Ordner gibt es folgende 2 Dateien die meiner Meinung nach in Frage kommen:

Sind das die richtigen Dateien? Aber welche werte muss ich da bearbeiten?

Freundliche Grüße :)

die Werte, um die maximale Lautstärke zu verändern, stehen in system/etc/default_gain.conf

ich habe gerade reingeschaut, finde da aber leider auf die schnelle keine Möglichkeit, die Maximalwerte der BT-Lautstärke zu beeinflussen. Bei den anderen Outputs sollte man übrigens vorsichtig sein - zu laut kann auch das Gerät zerstören.

In system/etc/ gibt es bei mir keine default_gain.conf :/

Oder muss ich sie selbst dort erstellen ?

Aber es wundert michm dass es keine einfache App gibt die die Mikro lautstärke etwas nach oben regelt. Für die Lautsprecherausgabe gibt es ja auch solche Apps.

Hallo,

schau dir mal die AlsaMixer app an.... die kann viel.

Ich bin damit aber NICHT zurecht gekommen.

Du kannst auch mal die Volume+ app probieren, bei manchen geht sie in Verbindung mit Bluetooth.... bei mir aber auch nicht....

Mia

Das File ist Samsung-spezifisch... dachte sie wäre auch in der Vor-S3-Generation vorhanden. Wenn es sie nicht gibt, weiß ich auch nicht weiter.
