Hi @jussi_laako are you also working with Qobuz, maybe for HQP Embedded/ HQP OS to support Qobuz Connect?
Qobuz app is really improving every 6 months that I check it. Quite nice at the moment.
Tidal Connect would be nice but I recall you wrote Tidal is not interested?
Hello
I have one question what is what?
cuda_cdev and cuda_dev because Iām a bit confused about all this.
thank you
best regards
It is on my list of things Iād like to do. Letās see!
cuda_cdev is the convolution/big operatrions device and coda_dev is the one for the rest.
So it is usually good to assign cuda_cdev the GPU that has more RAM (if thereās a difference).
Is there something that Qobuz Connect can do but roon cannot?
Iām curious. 
I guess it is mostly matter of tasteā¦ There are already four ways to play Qobuz to HQPlayer Desktop, and at least seven ways to HQPlayer Embedded.
And of course one can already use the Qobuz app with HQPlayer. So Connect would add just another path.
Similar to Tidal Connect.
When there is a new album/song released on Friday sometimes you wonāt see it in Roon until Sunday. Occasionally even Monday.
And then there is the obvious of some people donāt want to pay for Roon.
Qobuz app continues to improve and looks pretty slick. They are spending a lot of time on it
Great machine! Enjoy fiddling around the DSD 512 filters too! Can also run basic DSD1024 settings without DAC correction! For DSD256 you have all possible combinations! Suggest to use the new DAC profiles settings to make it easier!
I set up the May DAC, and DSD128 works with the powerless computer I currently have.
I assume the two green bars to the upper left show the computerās load.
When changing the fs to DSD256, the bars went crazy and produced no sound.
So, Iāll stick to DSD128 for a while. (Iāll try PCM later.)
Which filters/modulators would you suggest?
Thanks in advance!
Upper green bar is input buffer that is filled with source content, in this case pushed to by the HDSPe AIO. Lower green bar is output buffer that is filled by HQPlayer processing and where the DAC āpulls fromā.
Thank you for explaining what the bars indicate.
Which filters would be good for DSD128?
The DAC arrived a month sooner than expected, and I havenāt done any research. 
The filter you have for that content format, the default one, is good choice. Thereās some rough guidance in the PDF manual you could check out.
The modulator choice is one of the simplest, and you could check if you are able to do for example ASDM7 or ASDM7EC-ul instead.
whats the specs of your HQP machine?
Thanks again!
ASDM7 works, but ASDM7-ul causes the output sound to be chopped.
Itās a fanless computer equipped with Core i7-1255U.
Iāll replace this in a few months, but I have to use it for now.
ASDM7 is very good.
Iāve found the sound doesnāt come out simultaneously from the following two devices ā the May DAC (USB input) and Yamahaās CX-A5200 (coaxial input). I use Holo RED as a streamer.
If I want to use the USB input on the May DAC, I need to select on the HQPe Configuration page:
naa-xxxxxxxx: Holo Audio UAC2.0 Gen2.1 Enhanc: USB Audio
But there wonāt be any sound produced through the Yamaha AV receiver.
After trying several configurations, I figured out that selecting:
naa-xxxxxxxx: Holo Audio UAC2.0 Gen2 - RED: USB Audio
and changing the Mayās input to I2S, then sound comes out from both devices.
I use the above ātwo device outputsā during work, because I use two rooms: the main listening room for drafting and my study for typing. The Yamaha receiver sends music data to the study by using the Zone function.
So, in short, I wanted to say the Mayās I2S input can be useful in some cases.
You can now also achieve this with the new combo backend feature. But your current solution will certainly ensure better syncing since thereās only one audio device and one clock, and output format is anyway limited by the S/PDIF link to the receiverā¦
In some other cases using for example two NAAs would allow DSD outputs in multiple rooms, etc.
A post was split to a new topic: Does the āOutputā button on May DACās remote do something?
So, how are we finding the new EC modulators and sinc-Lh filter in 5.11?
Iām listening to ASDM7EC-fast 512+ and havenāt heard better transients in my system. Cymbals especially. I can do 1x sinc-Lh with DAC correction or sinc-MGa with DAC correction off. I prefer sinc-MGa but am concerned at the long term health effects of listening to an uncorrected DAC.
