Hi,

I have SlimServer running on an Infrant ReadyNAS connecting to a Squeezebox 3. Most of my music is FLAC and I was noticing occasional performance problems (stutter with rebuffering). Digging into the SlimServer settings, I saw that under file types, FLAC was both available as FLAC (built-in) stream and as WAV stream.

I tried disabling the WAV stream to force FLAC streaming and to avoid any transcoding, but then I couldn't listen to any of my FLACs any more. Now my question is: Shouldn't the Squeezebox 3 natively support FLAC? How can I find out what format is being used for streaming?

Thanks,
Martin

FLACs will be sent as FLAC preferentially if both options are checked.

Are you sure you have enough bandwidth? If the issue was transcoding, there would be a dropout before the buffer would drop to 0.

See http://wiki.slimdevices.com/index.cgi?DiagnosingPerformanceIssues the last section about Player Statistics. Run a few tracks and post Player Statistics.

Odd... it definitely should work. I listen to FLAC files on my SB3, streamed wirelessly from my ReadyNAS NV+ all the time - it works a treat. The only time I get dropouts is when I run an rsync backup of my laptop's hard disc, which uses up both wireless bandwidth and ReadyNAS CPU cycles.

Below are the Player Statistics. Just as a not, I am using a wired Ethernet connection on a 100/1000MBit network. (ReadyNAS is on Gigabit). I still don't understand why playback of FLAC files stopped working when I disabled the FLAC=>WAV option. Is this maybe a result of using one FLAC per CD with embedded CUE sheets? I had previously run Network performance tests an up to the highest throughput (5000kbps?) I got 100% performance.

Yes, you shouldn't have any bandwidth problems on wired.

It sounds like a ReadyNAS issue, which you might want to take up at the 3rd Party Hardware forum:
