I am looking for advice on anything else I can try to get a TonePort UX2 working on Windows 10. It crackles continuously during playback no matter what the buffer size, power settings, system load, which feels like a driver problem to me.
I think I can rule out hardware problems, because if I boot KX Studio (Linux-based audio distribution) on the exact same laptop, using the same USB port and cable to the same UX2, the audio quality is fine with the ALSA USB audio driver.
Computer is Acer Aspire 5536 laptop (Turion X2 processor) running Windows 10 Home 64 bit (10586.212.amd64fre.th2_release_sec.160328-1908). I have tried the following, and none of them have made any difference:
Clean install of Windows
Latest BIOS (Acer 1.11)
â€‹Latest Line 6 drivers (22.214.171.124)
Latest Windows updates installed
Power supply connected vs running on battery
Disabled WiFi adapter
Enable "high performance" power profile
Different USB port(s)
Different USB cable
Uninstall USB host controller driver and reinstall
Disabled hibernate/fast boot
Different sized buffers
Different sample rates
Set Windows default audio device to UX2 vs built in audio
ASIO UX2 vs ASIO4ALL
Any suggestions for anything else to try would be greatly appreciated!
