[pulseaudio-discuss] EnableSequence/DisableSequence in SectionDevice doesn't work on pulseaudio 13.xx

[Yang, Libin]

Hi Jaroslav,

Thanks for the patches. I tested the patches today and found the following issue. The EnableSequence/DisableSequence in SectionDevice works now but it only works when pulseaudio is initializing. After pulseaudio starts, when I switched audio from "Speaker" to "Headphone" in sound setting, for example, it will not set the corresponding controls. Comparing to the old pulseaudio, the controls will always be set when I switched audio from "Speaker" to "Headphone" in sound setting.

Regards,
Libin
