In case the problem happens to be pulseaudio crashing, please follow these instructions first: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment If you couldn't find any evidence of 'pulseaudio' crashing in the past then please try some slightly older (or newer) kernels and tell us if you find some that don't have the bug: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ** Changed in: alsa-driver (Ubuntu) Status: New => Incomplete ** Also affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete ** Summary changed: - [HDA-Intel - HDA Intel PCH, playback] No sound at all + [Lenovo IdeaPad 330] No sound at all ** Summary changed: - [Lenovo IdeaPad 330] No sound at all + [Lenovo IdeaPad 330-15IGM] No sound at all ** Summary changed: - [Lenovo IdeaPad 330-15IGM] No sound at all + [Lenovo IdeaPad 330-15IGM] No sound at all after resuming from sleep ** Tags added: resume suspend-resume -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827460 Title: [Lenovo IdeaPad 330-15IGM] No sound at all after resuming from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1827460/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
