我使用的是 Sony MDR-ZX770BN 耳机。连接耳机后,一切正常,但前提是我正在播放音乐。我可以连续几个小时收听 Spotify 或 YouTube,没有任何问题,但如果我暂停歌曲/内容,则需要大约 2-10 分钟才能停止工作。耳机没有丢失蓝牙连接,但在声音设置中,我看到“配置”插槽随着所选选项 A2DP Sink 消失:

有任何想法吗?
答案1
我认为我解决了这个问题。不确定哪一个有帮助:
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
变成wifi.powersave
2
sudo nano /etc/bluetooth/input.conf
放IdleTimeout=0
答案2
有时 A2DP 接收器会消失,只剩下 HFP。删除 /var/lib/bluetooth 也无济于事。每次清除 blueman、重新安装并重新启动后,A2DP 都会恢复。不知道为什么这对我有用。
