Roon's update sounds really good

The Ethernet cable is [also] a big problem. It runs long and can pick up low-frequency noise which cannot be filtered out.

It’s balanced, twisted, shielded, ground isolated. If it wasn’t perfect most offices wouldn’t function.

There's no way to get a network receiver in a device that isn't noisy. It happens. However, I agree that the cable itself can be a source of RFI/EMI interference, so it's good to route it away from analog interconnects and power cables.

I would imagine however that Ethernet, lacking an actual RF tranciever, would be easier to design a low noise interface to, but I've never had to do it.  I would take this information into consideration, but not without some skepticism. :)

Oh, lastly, Ethernet uses balanced, ground isolated connections by design. Ground loop issues are a real problem in offices and labs, given the long runs possible so the whole Ethernet chain is designed with this in mind.

However, routers and switches usually have noisy power supplies which can contaminate your AC line.

does the buffering take care of the interruptions like matching the clocks?
Yes.  Ideally, you have more data than is asked for.  Say 1 seconds worth.  While the input/output must be balanced, on average, it does not have to be exactly right all the time.  So, the DAC may continue to feed off the buffer even if the incoming data is randomly delayed by 0.01 or more seconds.

Hi @hshifi
So,  all internet traffic happens using TCP/IP. This protocol has source and destination IP addresses.  The only traffic coming to your router is traffic specifically sent to you.

Some of this traffic is of course malicious and intended to look for vulnerable services. The router behind the modem is responsible for blocking all incoming traffic that is unsolicited/unwanted.

Having said this, I have seen coaxial cables cause ground loops.  Having a cable isolator fixes these.

Best,

Why would you use wifi for streaming over wired?

 

Convenience, I don't have a great way to get the bits to the place over wired. Sorry I have disappointed you.

Oh, yeah yeah, I bought this new audiophile Wifi antenna, with a golden ratio double helix photonic quadratic grand unified theory of basilisk oil.  So long as I keep the basilisk oil topped off it sounds great! :)

Honestly I'm not sure what happened but I don't want to mess with it! :)

My best theory is that I moved from a channel that was more congested than the charts say. I found a completely unused 5 GHz channel and it improved my voice chat as well as my audio quality. Given all the built in buffering, etc. this should not happen.  In any case, I found the buffer size for the streamer and increased it to a full half second, hopefully this will reduce any more such issues.

Also changing my buffer size to a full half second.

Oh, wait, my bad, I know what happened.

I changed the router channel to use a less congested one.

I just hit the update button last night... but it seems like I am running 1.7 / 528 on the bridge
