Unless you want to upgrade your sound, than there is (and so i did, and thanks God I did)This is not what you want, there is no reason to send audio over HDMI on PC.

The all point of this is that there is no conversion at all. So it shouldn't affect the clock. And I can hear clearly that the sound is better (as you say it's in my head maybe, but what's really interesting to me is, how do you know for a fact that it's only in my head? when you, never heard, listen or did any testing on this card what's so ever?! Maybe it's in your head too)clock
The only advantage (sound wise) I have noticed with the USB is, when playing 32bit 384khz vs 24 192khz, and even then the low frequencies are not as good. It's very subtle but it's there.
If you read up on HDMI audio clock regeneration you'll find out about the practical problems with the clock. I'm glad you're happy with the result you've got, but please avoid misinformation on the technical side.The all point of this is that there is no conversion at all. So it shouldn't affect the clock.

In that case I must have misinterpreted when you said:I read a lot believe me or not. An there's no misinformation from my place
This is incorrect for the HDMI link from your laptop to the audio extractor board. That link packetizes the audio data and sends these packets in the horizontal and vertical blanking periods of the video data. There is no audio clock in the HDMI signal - the receiver needs to reconstruct it from the video clock and cycle time stamp. Doing this without significant jitter is tricky enough that papers are written about methods of doing it, and it shows in the jitter measurements of AVRs' HDMI inputs - I don't think we've seen a good one yet. John Dawson of Arcam covers their approach to this here starting on page 21 while Oppo cover it here. To be fair most of them get to 'probably inaudible' on jitter, and don't have exemplary jitter on their other digital inputs either.The all point of this is that there is no conversion at all. So it shouldn't affect the clock.
Lots of questions, I'll answer in details when I can. But basically I tried few different ways and audio sources when i connected the d90 to the HDMI to iis. I used Tidal, SACD, FLAC, youtube, Dj Traktor 3 even Spotify. I'm using a pre amp with crossover from Rockville (ppa20) then it's connected to the Atom JDS and to my hyperx cloud alpha or to my km750 who i connect my jamo 8. The range on the d90 with (the card) is between 44.1 to 192khz. What I have noticed is on all the platforms the bass is better only when i play a higher resolution (32bit 384khz) the sound stage is a little bigger but the bass is still not as good (the only thing that really bother me is, that on tidal, when i switch between songs, there's some tiny noise in the beginning)fabien32, I'm open to new discoveries and unconventional wisdom, so I'm happy and encouraged with your results ... but I've been around in hifi for many years, so I'm also suspicious of your results. It simply doesn't ring true that a high-jitter/non bit-perfect signal chain will sound better than a low-jitter/bit-perfect signal chain.
However I'm still keeping an open mind on this issue at this point, and I'm wondering if there are some additional contributing factors involved.
Can you give me some further information, please:
1. Can you give examples of the audio files you played? Artist, album, ripped from CD, hi-res download, etc.
2. When playing a 44.1kHz audio file, what is the sample rate displayed on the D90 front panel? 44.1kHz or "48kHz" ?
Do you have any 88.2kHz audio files, or any 176.4kHz audio files to try? What sample rate is displayed for these?
3. Are you listening via a JDS Labs Atom? What are your headphones?

Yes, but when you play a 44.1kHz source, does the D90 display "44.1kHz" or "48kHz".The range on the d90 with (the card) is between 44.1 to 192khz.
The Jamo S801?jamo 8

The Jamo S801?
Ah, upsampling is possibly why you are getting good results via HDMI.Usually the software take over the rate
Not only saying, I made a video for you to prove it. but apparently it's too big(237mb) . I can upload it via hugefiles service if you really want?So you're saying the D90 will show "44.1kHz" via HDMI?
