Hi Harry < can you have a look at the logs and see if theres anything obvious. The stuttering is the same on Wired and WiFi , the same on Roon and squeezelite. Standard wav and flac files.

Thanks

Tony

If both are enabled, WiFi takes priority. So, to test using Ethernet, first disable WiFi.

Thanks , yes I have already done that .

Hi Tony,

Your logs seem fine, except that I see quite a few ‘undervoltage’ messages. Have you changed power supply?

Anyways, make sure your powersupply is heavy enough, and for now I would recommend to use wired only and see how things are working out.

Ideally you only use one service, and as soon as it happens again you send me a fresh feedback.

Thanks

Thanks Harry

When it says under voltage does it give a number . It would help me identify the problem power supply . I have a 5v and a 19v powering the endpoint .

Thanks

Tony

Are you using a DAC Amp hat? The voltage warnings would be for the RPi supply, i.e. the 5 V supply.

It’s a Pi2AES

Do you have two separate power supplies, and is the 5 V a standard RPi 5 V wallwart?

I note that the Pi2AES can provide the 5 V, but you need to use a jumper. Maybe try this to see if there is an improvement, and to determine if the 5 V supply needs replacing.

Yes both linear power supplies , I’ll try and investigate

These are not as efficient as the switched-mode power supplies, and this could be why you have the under voltage messages and performance problems.

Swap out the 5 V with an official RPi PSU to see if this improve matters. Likewise, don’t be concerned about using a SMPS, especially on the digital side, since so called “switching noise” is way way above audio frequencies, and the RPi has clocks running in the MHz, too.
