Usbip perfromance over wireless link

Installing and Using OpenWrt
1

Hello everyone,

I'm using WRT190ACS with latest OpenWRT stable release 19.07.5. I was able to pair a USB sound card to my PC with usbip (downgraded libudev to version 3.2-1). The PC runs Ubuntu from flash drive using AX200 wifi card. It works pefectly fine using wired connection, while wireless link does not reach the same speed, and the sound becomes slow with minor pauses. I tried both 5GHz and 2.4GHz. I suspect that Marvell 88W8864 is unable to provide required latency, but I don't know how to confirm it. I'm attaching the graphs of traffic using wired and wireless connection.

usbpip probably isn't designed for streaming content.

If possble, install something more adequate, like mpd.

If the PC's only used for audio streaming (then why use a PC?),
there are other options like Mopidy or Volumio.
