Dear Khadas Community,
hello, have a nice day.
We have recently purchased a Khadas tone board for audiophile use and it’s an incredibly beautiful device, we are very, very happy with it.
However we have an issue:
after some music playback (Desktop PC with Windows7 64), a single loud sine wave tone (just like: “tuuuuuu”…) is sometimes played instead of music for a couple of seconds.
This problem goes on and appears randomly until we disconnect the USB cable from the Tone Board.
At this point the problem disappears for a while, until the “cycle” restarts somehow again.
Thank you very much indeed for any tip and suggestion, sincerely,
this is a known problem, due to the fact that you use an evaluation and restricted version of the windows audio driver for the ESS dac; search the forum for more details on that
Hello, I Agree with ravelo on eval driver. Uninstall the driver and use Window’s native driver.
Also, please post what firmware is on your TB now.
For more information, see here.
Hello, thank you very much indeed for your gentle support.
I’m sorry for the very late reply.
I have done every step of the firmware upgrade guide, but when I unistall the TUSBAudio eval, Windows stops to recognize the Khadas Tone Board: it disappears from the peripheral list.
So I can only use Khadas with the eval and with the “beeps”…
From here, " * **Uninstall the EVAL driver that you used for upgrading firmware, and re-install the v224 driver.
- Alternatively, if you’re on Windows 10, uninstall all Khadas-supplied drivers and use the native Win10 UAC2 driver supplied with the OS."
Looks like only Windows 10 has a native driver for the TB. Otherwise use the v224 driver.
If you have done the above steps and it still is working, I’m not sure.
