I had used Roland QUAD-CAPTURE on Ubuntu 16.04.1 without any problems. But it can't play audio suddenly since some days ago. I tried to fix this problem by un-muting devices, upgrading kernel, changing USB cable, but it still can't play anything.
Issues
- Can't play audio with Roland QUAD-CAPTURE on Ubuntu 16.04.1.
- Before, it can play audio without any problems.
- In another device, NVIDIA HDMI can play audio.
- It works on Windows. (it may not be physical device issue.)
