Description Vyacheslav Dikonov 2020-05-07 22:55:36 MSK 
После перехода на ядро 5.5.17-un-def-alt1 появился новый баг. Во время воспроизведения звука, чаще всего примерно на 30 минуте, самопроизвольно отключается SPDIF. 

Сразу после этого команда "sudo iecset audio on" выдает:

snd_ctl_elem_write: Operation not permitted


Через несколько секунд "sudo iecset audio on" включает звук обратно. В результате кино смотреть невозможно. Происходит это в Сизифе на ноуте со встроенным звуком hda-intel:

$ lspci | grep Audio

Похоже на сломанное управление питанием.

Comment 2 Vyacheslav Dikonov 2020-05-07 23:12:01 MSK 
Т.е. все опции драйвера по-умолчанию.
power_save = "0" 
Не должно быть отключений по таймеру.
