Problem: RPi4 with Official Touchscreen - Stuttering Audio

In the last couple of weeks I experienced music playback breaking up along side the UI (on the touchscreen) becoming unresponsive.

The RPi and Touchsreen along with a SSD and DAC are all running from a single power supply (3.5A). I've just susbstitued this with a RPi5 power supply (5A) in a effort to fix this (all good so far).

If that doesn't fix things, I was wondering if the 2GB memory is not enough for a Touchscreen setup? I also have a substiture 4GB RPi4.

Things have been working fine for at least a year in this setup, so I suppose some hardware may be packing in? I'm only playing files from the connected SSD.

I have a separate moOde based setup in another room, so I can start to susbtitute things should the new power supply not fix things.

Thanks,
Nick

I have an official 7-in touchscreen on an RPi3B+ / 1 GB at the moment with an external USB-DAC.

Running moOde 8.3.6 without the local display turned on, the moodeutl -m command shows about 20% memory consumption.

Turning on the display results in memory consumption roughly doubling, to 37%.

The numbers will vary but there's plenty of headroom.

We'd need more diagnostic data to get a handle on what's happening with your installation. Various logs are available.

Regards,
Kent
