Given all the various feedback, I think I'm just going to retire the SB3 out of the mix entirely. For the sake a Pi Zero + DAC I think it'll just make everything simpler to be running on similar hardware :) Thanks guys!

Well that's on the assumption that all the Pi are wired. Maybe I missed that statement. The LMS server would be sending 9 times that stream out, which still isn't much in reality I agree, about 7 Mbit/s. Transcoded from Matt's brain by Tapatalk -- Hardware: 3x Touch, 1x Radio, 2x Receivers, 1

But if the SB3 is alone on its 2.4GHz network, where's the problem? Still enough bandwidth to stream HD video so why not 48kHz FLAC? We are talking about 750kbit/s here. If you don't get that out of a WiFi network then it's so broken that even the control connection will probably no longer be sta

Lame encoding a single stream for a single group of players will run fine on a Pi. If you want separate streams all separately encoded then you might run into trouble. I might suggest setting a bandwidth limit on the SB3 to force stepping down the bitrate when it joins the group. Then unsync that

Don't do that. FLAC is fine and you've got enough bandwidth unless you do crazy stuff like streaming 384kHz sample rate material and such. Transcoding to MP3 takes a lot of CPU power and will likely create more issues than it solves. FLAC is perfect for streaming. --- learn more about iPeng, th

Brilliant thanks DrMatt, I appreciate the help. The reality is that while FLAC is total overkill for 7 or the 8 zones, it is how my music is stored. Part of why I'm trying to get my head around this is so I know what will happen under different scenarios. Based on this, if I place the SB3 to d

Codec support on the Pis depends on the software stack not hardware, and the SB3 is likely to be your limiting factor in terms of codec support anyway. Sent from my ONEPLUS A3003 using Tapatalk -- Hardware: 3x Touch, 1x Radio, 2x Receivers, 1 HP Microserver NAS with Debian+LMS 7.9.0 Music: ~13

There is no need to transcode at all if you are playing to a Pi. The resampling from 192 kHz to 48 kHz shouldn't be a problem either, the Pi only has to do it for its own player. --- learn more about iPeng, the iPhone and iPad remote for the Squeezebox and Logitech UE Smart Radio as well as iPe

Hi all, I'm setting up a multi-room system with 8 zones/players. I was asking elsewhere in the forum if 8 is realistic and the answers generally come back to bandwidth and whether the players can natively transcode the streams. I have no idea on the transcoding question so thought I'd ask if any
