> Can you tell some solution to this problem? Unfortunately there is no solution in sight yet. This looks like an issue with Lenovo's firmware, if any. Conexant chip itself has no such a feature, and the driver doesn't change the power state by itself. Takashi This is the reply from the author 8 months back. I forgot to post his reply here. Now I realize that it shouldn't be a Lenovo firmware issue because a few Toshiba laptops also affected by the same bug. Somebody can try mailing the author again if they want to. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1038479 Title: [Satellite L755, Conexant CX20585, Speaker, Internal] fails after a while Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: Restart will fix the issue, but sound always quits from internal speaker.
