My squeezebox touch was outputting what sounded like distorted/low sample audio on the SPDIF output which confused me because it didn’t seem to be loose and there were no issues further along e.g. with the amplifier

A reboot worked — and the Squeezebox touch can be easily reset over SSH

1. Settings -> Advanced -> Remote Login Menu on the Squeezebox touch and enable SSH — it will tell you its IP and the root password (1234 by default)
2. An old version of SSH is used. To connect:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c aes256-cbc 192.168.x.x -l root

where 192.168.x.x is the IP, will do it. On my network it is 192.168.1.103 on yours it will be different. The default password is 1234 3. Once SSH’d in, reboot will reboot
