[pulseaudio-discuss] [PATCH] pavucontrol: add support for AAC pass-through

[Akihiro TSUKADA]

Hi Tanu,
thank you for reviewing my patches.
I understood the (forward?) compatibility problem of the new encoding type.
I will revise the patch and re-send it
once the compatibility is solved / confirmed.

I thought at the beginning it would be alright because if 
(a) v3server -> v4client:
    enc.type >= PA_ENCODING_MAX at v3 should not be passed from server,
(b) v4server -> v3client:
    client should filter-out enc.type >= PA_ENCODING_MAX at v3,
(c) v3server <- v4client:
    server should ignore the received enc.type >= PA_ENCODING_MAX at v3,
(d) v4server <- v3client:
    client should not send enc.type >= PA_ENCODING_MAX at v3,
but those must be confirmed and
there must be lots of other things to check as you said,
including ext_device_restore/save.
