Out of curiosity do any of those suppoSHWrt anything else than MP3?<br>
I'd expect to use a more state of the art codec at high quality settings<br>
for an "intake" stream. MP3 even at very high bit-rates has its known<br>
problems.<br>

You're confusing two concepts here:<br>
- The global source password<br>
- authentication using "source" as the user name<br>
<br>
It is quite unfortunate that many a software (or in this case hardware)<br>
doesn't support username/password, but hardcodes the username to<br>
"source". This does NOT however stop you from having a different source<br>
password per mountpoint. Just don't define a username or set username to<br>
"source" in the <mount> definition.<br>

Personally I'd outright discard the RPi, due to its many design<br>
deficiencies and low performance.<br>
<br>
Coincidentally I've been recently looking into various aspects of a<br>
hardware based Icecast source, preferably open source hardware (OSHW<br>
conformant, rpi isn't), native Ethernet (USB based sucks), decent audio<br>
codec, preferably not just Line-in but also balanced inputs.<br>
I have some devices based on the Qualcomm Atheros AR9331 that use a<br>
decent Wolfson 8918 audio codec. While the codec is capable of also<br>
balanced and DMic inputs, sadly as such the devices are configured as<br>
output only.<br>
I also have, for an unrelated project, an AllWinner A10s based Olinuxino<br>
board on my desk. It at least has a line level input and native ethernet.<br>
I'm not particularly fond of USB sound cards, at least the cheaper ones,<br>
as their frequency reference is often horrible and on a professional<br>
setup the last thing you want is for your stream to run away after an<br>
hour or two.<br>
I need to do some more experimenting, but might consider prototyping a<br>
open hardware device that would fulfill all those requirements, but fit<br>
a budget. A likely target would be one of the recent open hardware<br>
boards that has native LAN and could attach a good, linux supported,<br>
audio codec over I²S or similar.<br>
<br>
Cheers<br>
