X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2^2^2~1

mixer-control: Only stream-id for bluetooth devices only

They're the only ones that merely flip ports and clearing it for
other devices breaks e.g. lineout and headphone combinations.

Fixes: 8bf60ee ("mixer-control: Reset `stream-id`s on UI devices")

Bug: https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/issues/40
