[Risolto] Microfono USB Webcam

Rèdeitramonti

Buongiorno gente,

Ho acquistato una webcam USB a basso costo, la funziona egregiamente per quanto riguarda la parte video. Tuttavia non si può dire lo stesso del microfono, dato che in tutte le video-chiamate che ho fatto non si sentiva nulla.

La webcam sembra essere correttamente dal sistema:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 05a3:9331 ARC International Camera

Cosi come il microfono sembra essere rilevato:

Tuttavia escludo tutti gli ingressi in Pavucontrol e mantenendo solamente il microfono della telecamera il problema dell'assenza di voce permane durante le chiamate permane.

Attualmente sul mio fisso v'è la versione di Ubuntu 22.04 LTS con ambiente LXDE. Qualche suggerimento?

Ho il sospetto che i microfoni delle webcam a basso costo non siano proprio il massimo, io sul desktop ho un Generalplus Technology Inc. 808 Camera e non la uso quasi mai. Se parlo, per sentirmi mi sentono (non benissimo, credo). Se registro quello che dico con OBS studio la qualita' e' molto povera. Infatti per le televideoconf in cui devo anche intervenire, o per le registrazioni, uso il laptop il cui microfono imbedded e' molto meglio/

Buongiorno,

Il problema è stato risolto. Semplicemente prima ho installato

Codice: Seleziona tutto

alsa-utils

e, da terminale, accendendo alle impostazioni tramite

Codice: Seleziona tutto

alsamixer

, ho attivato il microfono della videocamera.

Allego anche le informazioni relative alla videocamera, cosicché se un altro utente avesse lo stesso problema, tramite una ricerca online, può trovare facilmente questa (possibile) soluzione.
