And let us know if this has any effect on the issue at hand. There are four of those - all of them were already set to "auto" on boot (without me doing anything). HDA still stays active. Here is the dump of "power" subdirectories: /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/async:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/autosuspend_delay_ms:1000 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/control:auto /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_active_kids:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_active_time:226 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_enabled:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_status:suspended /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_suspended_time:117748 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/power/runtime_usage:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/async:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/autosuspend_delay_ms:1000 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/control:auto /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_active_kids:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_active_time:242 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_enabled:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_status:suspended /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_suspended_time:117725 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D1/power/runtime_usage:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/async:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/autosuspend_delay_ms:1000 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/control:auto /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_active_kids:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_active_time:275 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_enabled:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_status:suspended /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_suspended_time:117684 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D2/power/runtime_usage:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/async:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/autosuspend_delay_ms:1000 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/control:auto /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_active_kids:0 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_active_time:264 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_enabled:enabled /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_status:suspended /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_suspended_time:117664 /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D3/power/runtime_usage:0 /sys/bus/pci/devices/0000:01:00.1/power/async:enabled grep: /sys/bus/pci/devices/0000:01:00.1/power/autosuspend_delay_ms: Błąd wejścia/wyjścia // translates to: "Input/output error" /sys/bus/pci/devices/0000:01:00.1/power/control:auto /sys/bus/pci/devices/0000:01:00.1/power/runtime_active_kids:0 /sys/bus/pci/devices/0000:01:00.1/power/runtime_active_time:127936 /sys/bus/pci/devices/0000:01:00.1/power/runtime_enabled:enabled /sys/bus/pci/devices/0000:01:00.1/power/runtime_status:active /sys/bus/pci/devices/0000:01:00.1/power/runtime_suspended_time:5389 /sys/bus/pci/devices/0000:01:00.1/power/runtime_usage:0 /sys/bus/pci/devices/0000:01:00.1/power/wakeup:disabled</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
