It’s funny you say leave hyper threading enabled as over at the audiophile optimizer forum that is a big deal and it is advised that it should be turned off along with all of the speed stepping and XML profiles, I just never heard a difference between on and off with any of them. It was actually quite funny as I had server 2019 installed with AO and a stock standard windows 10 duel boot after the latest update to windows it sounded better than AO and so I stopped using it, then Daphile came around again after many years and the sound was so much cleaner, clearer and more precise than what I had been listening to it was the final veil lifted from my system.As In the last month I replaced my MiniMax DAC Plus with the MiniMax Supreme that was like taking a coyote sheets of the speakers, then I replaced my Audioquest Rockefeller speaker cables and got some Kimber Kable TC12 2 sets for bi wiring (cheap Chinese knock offs) but so much better through the whole frequency spectrum it was again like another sheet had been taken off the speakers. It has been a very good month.

Well, this is data being executed by the operating system so before any digital to analogue conversion.
The simple explanation is audio playback is not a real-time process, the application and operating system will load enough data into memory to ensure buffer under-runs don't happen which results in audio dropouts. This process is seamlessly maintained in the background.
You also have a multicore and multithreaded CPU paired with a multitasking linux operating system, this architecture allows Daphile to run as webserver using ethernet or wifi and send data to a USB DAC concurrently.
Therefore nothing to be gained by using a RT kernel.

The RT kernel is essential when striving for minimal latency, e.g. when playing midi keyboard or doing audio editing work. For pure playback where latency can be even single seconds it brings no advantage, actually it takes a bit more load and sometimes buggy drivers fail in RT setup. But audiophiles love the RT buzz so the author did a version with it.
Thanks, I thought as much.The data gets sent to the DAC and the DAC then takes over and as long as there are no audio drop outs then in regards to the data getting to the DAC everything is fine, I didn’t fancy setting up another Daphile install.
Can someone explain a couple of things under system status
1) Temperature has 7 readings and I hav an 8 core(hyper threading) where is the other one?
2) System load reads 4.46 3.59 3.11 atm obviously it changes under different circumstances but what does it mean where can I find more info on this.
Convert PCM to DSD enabled, DSD 256 use only this DSD rate selected. Clans-6 very high, Linear phase

8 processing threads with hyperthreading means 4 physical cores. + 3 temperatures for other parts of your system (GPU, chipset, etc.).
E.g. Understanding Linux CPU Load - when should you be worried? | Scout APM Blog or Linux Load Averages: Solving the Mystery
not all core temps are listed IMO, I'm using a 12 core; the first two temps on my system are from the Solarflare network card I'm using, a couple of temps showing are from the CPU and a few from somewhere else (guessing at the MOBO, perhaps the MB power convertor).
System loads are showing in Linux format, your numbers seem high to me though that may well be due to utilization of the CPU by converting to DSD ....Previously using an 8 core CPU my numbers usually were below 1 listening to un-adulterated PCM FLAC or WAV files.

Thanks for the reply it, is much appreciated do you have any advice on enabling any of the PCI device runtime power management I am especially curious about the DRAM controller. Thanks
I have read through the article’s you linked to and from my understanding of it having 8 cores, 8 would be % Linux Load Averages: Solving the Mystery. 100 so if my load shows 4 that is %50 load which is about what I get under same circumstances in windows, temps are fine at an average of 35 degrees and everything runs fine(no audio drop outs). Also the only thing that is slightly slow is at startup when it scans the media library what settings can I change to reduce/ stop this but still see any new files added while in windows, I have 8GB ram and i7 4790k cpu all my music is on the internal HD’s in the pc running Daphile (installed on USB)I connect via direct Ethernet cable from control laptop to PC. Once I have a good understanding of the settings I will be creating a manual/ guide for others as try to get specific details for Daphile is like trying to find rocking horse ****, Thanks I appreciate that your time is valuable

Thank you, you would think that in all the time Daphile has been around there would have been a better organised source of information regarding the settings and other general information
another question! If i use the create new installation feature does it clone all my settings or is it a fresh start, will it have the initial setup F1 option and if it does after that are the settings from the other installation still there, I would hope it would clone the install as otherwise you may as well just start from beginning again.Thanks in advance
the reason i asked the last question is i tried it once and it made it so i needed both the usb drives in the pc to run Daphile after that, as neither would work on their own.
I have a question about upsampling Spotify in Daphile
Hi folks!!! I am a new daphlie user. I managed to run Daphile in a Lenovo Thinkcentre core i7 7th gen, 16gb RAM, 512g SSD, with spotty for spotify connect.
I have an OPPO BDP-105 connected through USB to Daphile. I am able to listening music from Spotify through the OPPO DAC.
I am new in the "digital audiophile world". I would like to know which is the best configuration for listening Spotify in this way. Looking at the OPPO USB DAC input information, it seems like the Spotify music is being received as LPCM 44.100 khz. Is this the best option?
Sorry for my ignorance on this, but could I upsample spotify music to get a "better" bitstream at the OPPO DAC? (DSD, DoP, ...).
Thank you very much for sharing your experiences!

You can upsample but the “quality” will be the same. You could eventually hear differences due to how the Dac handles the stream, some of them resample all to dsd before conversion, or upsample, or even down sample dsd to some pcm form, and if they have different converters for dsd and pcm the result can be different.
Long story short, you cannot improve the source by up sampling but it could have an effect depending on system, you can play and settle for what’s best for you. In Daphile setting you can set the output sample rate.
Thank you very much for your answer. Where could I change the output sample rate in Daphile?

Hello,
Fairly new user to Daphile, long time hifi enthusiast..
So, I've installed daphile 21.04 on a 10yr old Athlon pc and am using its optical output, into Chord M-Scaler > Dave.
Having read about the high end Pcs with specialist power supplies
and USB card add-ons, I decided to try to upgrade the pc power supply.. and ordered the Corsair RM850x due to excellent reviews, low ripple, and general availability. And it's 10 year warranty.
Anyway, it's been running for 3 days now, and I'm happy to report that in MY setup, it's more than a worthwhile upgrade. While I did expect some improvements over the 10yr old ATX power supply, what I did not realise was that the old power supply was feeding noise back into the system.
YMMV, but for me, a really very good upgrade..
Meanwhile, I've sourced a second hand Phenom X4 CPU to replace my 2 core Athlon CPU, hoping it will speed up the interface, but I doubt it will make any difference to the sound.
Cheers.
