In last days I tried RuneAudio with USB output to my Burson Conductor dac. The result is stunning with 16-bit / 44.1 KHz files! The problems have occurred, in my case, with high-resolution files: 24-bit 48 Khz and above: i have pops and clicks during playback.

I tried some work-around founded in this and other forums, such unbind the DAC from USBHID, but without results. While I'm searching over internet, I came across this threads:

http://forum.odroid.com/viewtopic.php?f=117&t=21430 and https://github.com/hardkernel/linux/commit/43863e1417013a174e0c7cebcb32a8346c622cc6

in which, although it refers to a Odroid C1 bug and to the 176 kHz frequency, has been fixed the Odroid driver. Frank, I don't know if can be useful or if you were already aware of, but I must point out the same.

Thanks

From my testing experience,
USB compatibility is the core issue to be fixed.
Others nearly perfect.

I have the same issue as @JusticeAngel when using external DAC via USB connection.

I used the external DAC boards (PCM5102, ES9023 based) via I2S insteads. They played perfectly.

For PCM source, there is no problem.
For DSD source, as DoP only works for USB.
Playback DSD file need software converted to PCM within RuneAudio, it limits overall sound quality.

The issue at my case with external DAC via usb is:
16/44.1 : distorted
24/192 : very nice sound
DSD : distorted both Native / DoP

So playing external dac board via I2S connection instead now https://r.tapatalk.com/shareLink?url=ht ... are_type=t

Hi smallfat,

Hope USB compatibility issue also be fixed.

The only thing i can do, is to install the latest kernel from arch linux.
