[pulseaudio-discuss] raop no sound

Tue Jan 14 20:59:34 PST 2014

Hi Hajime,

>> Hmm, you are right. Your device seems to understand the TCP version. I

>> Unfortunately I don't have any experience with TCP version of the

I do not have mdns in my system - it is part of a somewhat larger .local
dns setup, and there are a few systems that dont speak mdns at all or in ridiculous
ways

>> - If you have paprefs command in your system, launch it and enable

I already checked that box, but I am not sure how much difference that actually makes
(if there is no auto-discovery)

>> - Attaching a log would help us understanding the issue more precisely.
