HQplayer 4 and Mac-mini M1

[ripples]

does anybody have this SDM issue with M1 or M2   ?  on my M2 Pro i get HQPlayer desktop using the CPU on 100% .

i have to kill the process via command prompt. 

 

this only happens with  poly-sinc-lp and  44.1 source material to  dsd256.

no issue if i use.  poly-sync-lp-2s, poly-sinc-ext2 ,etc.

That filter is a CPU hog and can take forever to initialize. Just use the 2s version.

thanks for the feedback, helps to clear things up as i'm investigating the M2 waters🙂

 

things start to lite up ,

sending from M2  to NAA  , below helps  me getting a more relaxed sound (YMMV)

sudo sysctl -w net.inet.tcp.delayed_ack=0

Out of curiosity, are you setting this on the M2 or on the NAA or on both?

I only configure it on the  M2

 

my network is mostly Wifi:

[m2]--->isp wifi router--->tp link (wifi bridge)---//rj45-->naa --//usb--->dac

 Sinc-lp,  Sinc-Long-lp  is a no go,  initialization takes for ever on m2 pro 

for reference my old i7 8th gen windows laptop has no issues with those filters using hpq 5

also sounds better compared to my m2 pro using NAA. btw this relates maybe to my lack of macos knowledge . Mac looks like linux but does not respond like linux 🙂 

 

just guessing dont think apple silicon has the tricks required for this

seems you're referrng to poly family, not new Sinc filters introduced in 5

indeed poly-sinc-lp,  poly-sinc-long-lp

At the same target rate? Because it depends.
Those filters have very high memory requirements for 512+ rates, but -2s versions work fine at those rates.

both laptops have 16gb ram dont think it is mem limited. it is some specific apple silicon thing with  poly-Sinc-lp, poly-Sinc-Long-lp

O/S DSD64 files to DSD256, when I pause the playing, I can just hear very faint, random "ticks" (like tiny scratches on an LP)

no clicks on that scenario , hardware: [macbook M2 pro/ventura 13.4 +HQP-Desktop and Client v5 + external ssd attached)] -->wifi-->NAA(windows)-->Dac

 

i use 250 ms buffer, small buffer can sometimes mean  sound is dropping unexpectedly but nothing like a click

So, the possible culprit is an upgrade to Ventura (other than HQP upgrade).

could be , interested in your findings 

 

btw my own experience  with "clicks"  relates to usb asio  installations on windows NAA (something from the past btw)

With the M2, a set of 8 performance cores are used while the other 8 sit relatively idle.  Then they switch and the other 8 cores get heavily loaded while the first set of cores sit with very low usage.

did you explicitly  checked the box for  "multicore" ?
