31  Ultimate Audio Playback / XXHighEnd Support / Re: Some MQA tracks play at low speed on: March 19, 2021, 07:44:35 am
Hi Peter,

To give an example Gretchen Parlato-Flor MQA is 24/88.2, track no 7 plays at slow speed. All other tracks are ok.

Unfortunately the Jethro Tull MQA albums, mentioned earlier, have been deleted so I don’t know their details.

Best regards,

Arvind

This album plays all tracks at correct speed for me.
MQA 24/88.2  bit rate 4233

Regards
Colin

The Chaka Khan album is one claiming to be MQA44 but plays at 1411 bit rate. If I switch off MQA Decoding the tracks play to their end so the problem is clear now.
I do have MQA44 albums that play correctly at 2116 bit rate so its only the bit rate that identifies the problem albums.

The Chaka Khan - Echoes of An Era I mentioned at start of this topic is MQA but I have downloaded several recent MQA albums which play OK.

I will try dowloading again

Anyone tried Chaka Khan - Echoes of An Era.

For me each track plays ok until near the end but jumps to next track prematurely. Does not happen with any other album.

There are quite a few albums on Tidal which I can't find with the XXHE search despite careful typing and trying various ways of including the * symbol.

For example:-
Artist:- Chick Corea*
Album:- *

Returns just one album but there are many on Tidal

Not sure if this is a recent issue or not.

Sad to hear of Chick's passing but his large volume music lives on. He played with many of the great musicians from Miles Davis to Bela Fleck and beyond.

A couple of my favorit albums:-
My Spanish Heart
Return to Forever - Romantic Warrior

Superb sound quality from the original 1959 takes, excellent digital transfer and interesting takes.

43  Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: Setting CPU core count with a twist on: January 24, 2020, 07:56:07 am
Peter, All,

I have come across some settings that have a really significant and generally posertive impact on sound quality. Might even be a candidate to look into / exploit in 2.11.

It relates to varing the number of active CPUs set in BIOS. Its well documented that the number of CPUs cores set active in BIOS can be used to tune sound, particually the case for 621 chipset montherboards.

The following simple additional step to core setting really supercharges the effect, certainly on a 621 motherboard which is what i'm using here at the moment.

There are two steps:

1) set the BIOS to a desired number of processors cores and tell XX/OS software that this has been done via reboots into XX un-minimised full OS mode. Nothing new at all in this step.

2) now add a futher processor core in BIOS setting but do NOT tell XX/OS sofware that this extra processor has been added by NOT doing the reboots into full OS mode.


To explain the the setting applied by the steps in a little more detail


Step 1)

Go into BIOS and set a number of active processors. The number of cores you select has to be at least 1 processor core less than the maximum for the CPU. So in my case with a 16 core 6130 cpu, for step 1) I can set the number of CPU cores  anywhere upto 15 for this first step. After setting the cores in BIOS, reboot XX / OS back to XX unminimised level so that the OS / XX recognizes the new number of cores that have been set by the BIOS. Now go back into XX minimised OS ready to play music as normal. All this is just the normal approach to changing the number of cores used be the PC for XX music playback.

Its a good idea to play some music now just to listen to how this sounds before the next step is applied just so that you can appreciate the change the step 2) brings.


Step 2)

This is the extra step. Now go back into BIOS and add one extra core to the number set in step 1). In my case with my 6130 set in step 1 to 15 cores I now set the core count to 16 in bios, save this and reboot. (The key here is just play immediately dont go through the reboots to tell XX and the OS of the change to add this extra core).

Now listen again.

Having applied this, in my system everything tightens up throughout the spectrum, highs are particually improved with real shimmer and sparkle. Speed and dynamics are excellent and the "realness" level of the music takes a nice step forwards. Its not a subtle change.

So far I have tried the setting with 15 cores in step 1) and 1 additional core added by step 2). I won't go into the detail of why but I suspect other combinations such as 10 cores step 1) and 1 core step 2) etc will also produce a similar effect, but as long as its just 1 additional core added in step 2) I think this should work.

It would be interesting to hear what people make of this way of setting cores.

Best regards,

Nick.

Curious as to what is happening here, after step 2 Windows sees all the cores again so nothing different as far as Windows is concerned (Windows always boots to what is set in bios). Maybe XX 2.10 runs differently I don't know.

Anyway my test will be to Unminimize OS & minimize it again without changing bios and hear if sound quality changes/gets worst.

Colin

Hi Peter

For me its nothing to do with format change, it happens with all tracks in the playlist are same format.

Hi Peter

I have this problem, the last track stops playing prematurely. This is with SFS=4. I have reduced to SFS=2 to cure the problem. But sound quality not so good. Any news on 2.11 to fix the problem.

Regards
Colin

Hello Zheng - Happy New Year indeed !

I solved this a few days ago. All you now have to do is wait for the new version. Wink

Btw, I think it is not commonly known by others which recognize the issue as "the last track in the playlist", that this happens at a "Format Change". So in the middle of the playlist it can happen just the same, if only a next track is of another Sampling Rate than the current one. The current one now will cut (and for how much depends on the SFS).

Kind regards,
Peter
