yeah, nice to hear, but that says nothing about the source. In Fact an CD offers 16Bit at 44.1 KHz there are only very few CD's with 24Bit and a higher sampling rate that you are requesting is only at DVD's (or SACD) available (because bigger Stream Size), but there are not so much Music DVD's available.
Studio Equipment is in most situations recording in ultra high quality .... BUT it is nonsense to mix Music from CD to a High Stream Recorder.
Of Course you can use EAC to rip Vinyl into 24/192 but therefor you need an High End Turntable incl. Pick Up.

Otherwise you can use dBPoweramp to blow up your 16/44.1 To 48KHz and 32Bit.

Google for SPEK and read how to determine what your files are really containing.

So, in my opinion every home equipment is using standard and normed sampling rates and you have to feed sonos with usual rates .... btw, keep in mind that 54Mbit is something around 5MB/s and every WLAN Device logged in is reducing the stream like 4 Devices = 1.25 MB/s the Data Stream of an DVD is round about 1.5MB/s, a CD something like 0.167MB
So I am wondering what you are trying with 24/192 @ WLAN ..... 2 Channel X 192KHz x 24Bit = 9.216 kBits/sec ...

BTW ... This should be the reason why Sindre Mehus is not answering, the Basics of digital Music is not his cup of tea :wink:

Thanks for the basic educational program. My Sonos system is extra. When too lazy to run the main one. The basic system consists of the OPPO BDP 105D AF firmware and AZUR 840a. The second system uses OPPO 203 AF firmware and AZUR 851a. Believe me, I hear all the nuances on this equipment.
As a Wi-Fi, I have 802.1ac and I can select the necessary band without any problems.
I have a rather simple question - how to make an entry transcode a FLAC for the Sonos. Unfortunately, I am not a programmer at all.

This is a commercial product. For it they take money. And support can take the work to at least something to answer the question of the buyer.

Please forgive me for my bad english.

English is also not my native language and I assume really faulty ....
Anyway I'm using this Software.
https://www.dbpoweramp.com/dmc.htm
There is a free Version available, but I'm using th paid Version. There you can change to almost everything you like. A couple of Plugins are for free download.
Hope this will answer your question. I don't know about SONOS. I have an Raspberry with an DAC Board connected to digital Input of my Old School HiFi Receiver. All my Lossless Music is going by Apple Airplay to that Device ....

Thank. I have no problem re-encoding any number of files, but this organizes a PARALLEL library. Sonos has a hardware limit of 50,000 tracks. Also, it does not support the DLNA. As a gasket between the network storage and Sonos manufacturers (Sonos and Subsonic) recommend the use of Subsonic. There is no limit to the number of tracks. Subsonic is capable of transcoding without changing the composition of the main library. By default, it creates mp3 stream. The developer reports that he can implement FLAC stream. That's what I want to customize.

I see, that's two times very special.
First the 24/192 and of course on the fly transcoding and on the other hand the Sonos System.

Sorry for waisting your time.

So use Google and search for ffmpeg, download the 64bit Version and put it in subsonic\transcode\
That Software is not part of SUBSONIC, servicing your system is your challenge.
