當我將耳機配置為特定配置檔案時（我喜歡使用高保真播放而不是耳機單元）Bose QC35 藍牙耳機,帕武控制不允許我將其配置到該設定檔。即使 pavucontrol GUI 顯示我已將其更改為高保真播放，重新打開 pavucontrol GUI 顯示它又回到了耳機單元。
這僅適用於我的藍牙耳機。更改配置模擬立體聲透過 pavucontrol 工作。
我可以使用以下命令查看我的耳機的配置文件列表pacmd ls-

直到幾天前我還可以手動切換配置文件，但現在配置文件的可用性似乎未知 -
[reik@reik-msi ~]$ pacmd set-card-profile 2 a2dp_sink_sbc
Failed to set card profile to 'a2dp_sink_sbc'.
和
[reik@reik-msi ~]$ pacmd set-card-profile 2 a2dp_sink_aac
Failed to set card profile to 'a2dp_sink_aac'.
有沒有辦法解決這個問題？
