Перезагрузил ноут - исчезли из Audio Output беспроводные USB-наушники.
Причем при загрузке или вставке usb-модуля слышен звук подключения наушников. Но как устройство не обнаруживается и, следовательно, нет звука.
На Windows определяется как и прежде, т.е. проблема не в наушниках.
Переустановка ALSA и PulseAudio не помогла.

Вчера перезагрузал, все было ок, а так все время ноут в сон пускаю. Никаких проблем не было.
Куда можно капнуть?
