We have recently purchased a Cymatic Audio LP-16 USB audio interface but
are having issues using it in our setup – an updated Windows 10, AMD Ryzen 5 1500x.
The unit seems to work perfectly for some amount of time – usually
2-15mins – but then suddenly no sounds are audible for 2-3 seconds.
After this short loss of audio the sound returns and is fine again for
another random amount of time. The sound is lost, not delayed – as if
the volume was temporarily muted.
While there is no audio the configuration UI volume meters also show no
sign of any audio being played – even though audio is supposed to be
The issue happens with both the ASIO driver configured for 18 channels
output as well as the WDM driver, for example while playing audio from
We have tried:
– turning it off and on again
– turning the computer off and on again
– switching the USB cable from a USB3 port to a USB2 port.
– switching to another USB cable
– switching to another power supply
– both firmware versions available on the web page, as well as what the
device was shipped with (unknown version number)
– both driver versions available for download
– playback at 48Khz and 44Khz
Unfortunately the issue persists.
We have borrowed a uTrack24 to see if this unit shows the same tendencies as the ones described above.
After some tests, the conclusion is that the two audio interfaces have the same errors: Sometimes when the PC boots, the Cymatic audio interface (ASIO driver) does not see the card/does not find the audio interface. Same time, Windows actually DOES find the interface and can play sound over WDM and ASIO4all. Reboot of either the interface the PC often solves the problem. uTrack24 also – sometimes (periodically, not very often) – drops audio for a few seconds, normally using the Cymatic ASIO drivers. Sometimes, when the interface is not recognized by the Cymatic ASIO driver, a restart of the Cymatic ASIO driver can be provoked by pressing some button in the interface GUI once or several times – and then the interface is available through th Cymatic ASIO driver.
When the uTrack24 has been turned off for some time, it shows more tendency to crash than when it has been running for hours.
HELP, or suggestions, or some kind of feedback would be highly appreciated.
Please tell me your OS version number, and the length of the USB cable what you are using to connect.
Those connection issue most of the times are caused because of the long USB cable.
Could you please make sure you are having the same issue with the provided USB cable as well? (1meters)
I have tried multiple short cables. When the Cymatic asio driver fails the inputs and outputs disappear. I can select the asio4all driver in my daw and the inputs and outputs reappear but playback is is glitchy. The Cymatic asio inputs and outputs won’t reappear until I change the sample rate in the Cymatic driver setting window. I am running Windows 10 Home edition.
We have no new driver releases in cue.
I just wondering this issue what you had on your computer it might be some driver conflict.
Could you please try to disconnect any other audio interface and/or uninstall asio4all driver?
Hello Laszlo, I have uninstalled asio4all and the problem still persists. One thing I have noticed is when I unplug the USB-C power plug from my laptop and run on battery the interface becomes stable with no pops or clicks.
Okay that’s an useful information.
Somehow this looks like an ground loop issue.
Could you please try to connect the uTrack24 to the same power outlet where your laptop connected, or if you have already there connect to different power outlet?
