Title: [82A1, Realtek ALC287, Speaker, Internal] Underruns, dropouts or crackling sound Status in alsa-driver package in Ubuntu: New Bug description: Hello, I'm using Ubuntu together with Windows on my laptop. If I boot in Ubuntu after Windows sound doesn't work well (instead of system sounds I can hear only shot noise). To fix the issue I need to completely shut down the system (call Power Off via Ubuntu GUI) and then boot again in Ubuntu. Please note, that reboot (called via Ubuntu GUI) doesn't help to fix the issue. Expected result: sound works well regardless of boot history. Actual result: every time I boot in Ubuntu after Windows sound doesn't work. Issue occurrence: 100%.
