Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de commutation audio pour un terminal, et un dispositif électronique, appartenant au domaine technique des communications. Le procédé de commutation audio pour un terminal consiste à : surveiller s'il existe un appel entrant ou sortant ; si tel est le cas, acquérir l'état de fonctionnement d'un module de traitement audio dans un terminal ; si l'état de fonctionnement est un mode numérique dans lequel un signal audio numérique est transmis entre le terminal et un dispositif audio et que l'opération de conversion analogique-numérique et/ou numérique-analogique est accomplie dans le dispositif audio connecté au terminal, exécuter une commutation à un mode analogique dans lequel un signal audio analogique est transmis entre le terminal et le dispositif audio, l'opération de conversion analogique-numérique et/ou numérique-analogique étant accomplie dans le terminal. Dans les modes de réalisation de la présente invention, lorsqu'il est surveillé que le terminal reçoit un appel entrant ou émet un appel sortant, l'état de fonctionnement actuel du module de traitement audio est défini en mode analogique, ce qui permet au terminal de fonctionner en mode analogique avec une qualité de communication garantie.
