The system was fine in the last two years. After updated the Roon last week, it played music normally. But finished playing one track and it stop to load the next track. It needs about 30-40 second to go to the next track. The tracks are in the same album.
That is an issue right there. Roon highly suggests that an SSD be used for the database. That on top of the under specc’d cpu is only going to cause issues.
