I'd been trying Linux on and off over the last 5 years ago with a spare Z20t I have and thought I'd put in some recent findings that might help with this issue.
Z20t-B and z20t-C models seem affected the same, with Ubuntu and Arch based installs - also tried various kernels from 5 through to 6.7. An interesting finding with one of my spare Z20's, is that when I wiped and decided to try Windows again, (tested with Win8, 10, and 11), this same situation is reproducable: - Power on, Speakers produce sound - Put to sleep - Wake from sleep, Speakers don't produce sound I found that there's an issue with the latest drivers from Toshiba/Dynabook, even for Windows: 1. Conexant Audio Driver > Posted Date: 2018-05-21 | Version: 8.66.47.56 2. Conexant Audio Driver > Posted Date: 2017-12-19 | Version: 8.66.47.50 | Size: 83.52M The driver from 2018 has the 'sleep-wake speaker not working' issue. But installing the 2017 version works totally fine. Hopefully this may provide some insight on this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1612916 Title: [Tohsiba Portege Z20T-C] Internal speakers don't work after standby To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1612916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
