Michael, it wouldn't hurt to update your BIOS to the latest (now. 6.30), given it includes multiple, high severity security vulnerability fixes.
Once done, could you please advise if this changes anything, and post the results of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date If still reproducible, to keep this relevant, please attempt a suspend via live environment of http://cdimage.ubuntu.com/daily-live/current/ and advise on the outcome. ** Changed in: linux (Ubuntu) Importance: Medium => Low ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete ** Summary changed: - Internal speakers don't work after standby + [Tohsiba Portege Z20T-C] Internal speakers don't work after standby ** Description changed: - I've a Toshiba x20t-C-121 (Skylake m7-6Y75 based).
