Subject: sink, source: Send notifications when flags change
X-Git-Tag: v3.99.1~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4096989ad6d9c6c36c90fe109a471946289ec931;p=platform%2Fupstream%2Fpulseaudio.git

sink, source: Send notifications when flags change

The hooks aren't currently used, but for example, the D-Bus protocol
could use them if it implemented flag change signals.
