Hi,

I have recently been using Archlinux with standard kernel 4.6.2 on a Toshiba Z20T-B (Intel Broadwell). After using suspend to RAM (S3) no sound is output from the laptop speakers. (systemctl suspend) The headphone jack behaves normally. Even after suspend. Restarting pulseaudio, killing it etc does not work. Pulseaudio registers no errors and tries to output sound to speakers as normal. aplay -D front:PCH also reports no errors, but fails silently. Suspend on Win10 works with sound resume, so it should not be a hardware or UEFI bug.

Best regards,

Max Zhao
