So I recently got a pair of R-51PM's and when using the USB A to B cord with my desktop the audio has a 1-2 second delay with youtube, windows speaker test and volume ding when adjusting, movies and spotify etc. Is there a reason for this or am I doing something wrong?
My R-41PM speakers are connected to my Macbook Pro 16" running macOS 10.15.7 via USB. It seems that the speakers are somehow sending the Mac a constant volume down signal when connected. This manifests itself when attempting to reduce the volume using the keyboard buttons, where the volume jumps down several notches per keypress. I've uploaded a video to YouTube that demonstrates this. In the first part of the video, where I press the volume down key 3 times, which reduces the volume all the way to muted (instead of 3 notches). I've tested & confirmed this issue on a brand new M1 Macbook Air running macOS 11.2 - however, I was not able to reproduce it when connected to a Windows PC. In the second part of the video, I'm using BetterTouchTool to attempt to record a keyboard shortcut. As soon as I focus the input box to record a shortcut, it detects that "volume down" is being pressed, even though I don't have any keys pressed. Both of these behaviors stop when I disconnect the speakers. Update: it's also preventing my display from sleeping automatically as it should. Unplugging the speaker via USB & moving it to an analog cable has fixed the issue. It's disappointing not to be able to use a USB speaker via USB, though.
Since my Klipsch R-51PM powered speakers have a built-in DAC and a 100% digital amp, I wanted to keep the signal digital throughout the entire pipeline -- so I figured I'd use the USB output on the Raspberry Pi 4. What I'm trying to ascertain is whether there would be a quality improvement if I used a HAT with Toslink Audio instead of the USB output on the Pi? (my Klipsch have both USB Audio Input and Toslink) FYI: I'm not networked -- just playing music from a USB Thumb Drive using Moode on the RPi 7" screen. I appreciate any wisdom!
