Anybody here with a Holo Spring 2 DAC? I was told it is using an XMOS U216 chip and it seems it is not compatible with JCAT USB Femto card, and it is not compatible with other audio optimized cards too. I tried it with several different PCs, software, cables, power supplies, reinstalling drivers few times, all PCs are compatible with the DAC with their original USB ports and I can use the DAC with a Singxer SU-1 and the audio USB cards. Tried all the different PCIe slots but no difference. All the audio USB cards work with an USB stick and external SSDs, HDDs. I completed the upgrade of the Femto card too, but did not help. 

 

The PCs can see the DAC, can change its sample rate accordingly but the ASIO initialization fails and no sound when click on the Play button. 

 

Any similar experience? Any idea what to do? Thanks for any help. 

 

By the way, I just started to use the Femto card and really like it.

Hello,

 

Thanks for the  report.

It works as Wasapi device. It does not work as ASIO. I can use it with Jplay in Classic mode, thanks for your help.

This means the issue is not likely related due to  the use of  JCAT USB Card  FEMTO. I'd try reinstalling DAC  drivers.

I did not think it is a Femto card issue for sure, as the DAC does not work with other USB cards, like PP v2 for example. I just wonder if anybody aware of this issue. Can be the problem of the XMOS U216? 

I tried the reinstall of the Holo driver, did a firmware upgrade too, but did not help.

 

Anyway thanks for your help.

Not likely. Is there a different driver available?  If so, I'd try it.

I just got the info from Magna HiFi that Holo Spring 2 needs a firmware upgrade to work with those mentioned USB cards (JCAT USB Femto included) properly in ASIO and they are now working on it.

Hi Marcin, and fellow Jplayers.

 

Have dual PC setup from the early days of Jplay, upgraded to FEMTO Jplay and Audio Optimizer V3.0 on Win 2016 Server.

 

Now considering adding a FEMTO USB card to replace PPA Studio V2. Will adding the FEMTO USB invalidate my AudioPC Jplay and Audio Optimizer Licences and have me having to re-install and use up one of my allocated Licence keys for each of the products?

 

Thanks in anticipation

Frizzup

Hi Frizzup, 

 

No, it will not invalidate your licenses.  NET Card might,  but then it's no problem, I can reset the counter for free.

 

Please let me know if you have any further questions.

 

Regards, 

Marcin

Hi Marcin, how are you? I've already begun developing and building my new desktop with the new power supplies, and soon I must inaugurate a topic to share the evolution.

I have a question regarding JCAT cards. Some time ago I asked if I could feed them internally with only the 5v power supply, and you answered yes. Said the card doesn't use the internal 12v provided by the MOLEX connector. Up to this point, everything perfect. My question now relates to GND (black) cables. The MOLEX standard has two centralized GND connectors, but I believe that only one of them is directly related to the 5v power supply. To power the JCAT cards, should I use the two GND cables, or just one? I thought of trying to leave only the GND that is next to the 5v path, but I'm afraid to interrupt the power supply and damage the JCAT card somehow.
