New install or power-wash the chromeos device with no plugged peripherals and sign-in. Plug External display, 3.5_audio_jack, and USB in sequential order 2. Unplug and Re-Plug 3.5 headset 3. Manually select 3.5 as active node and suspend/resume the device 4. Manually select External display as active, then reboot and sign in to the device again 5. Manually select USB as active, and unplug the USB audio peripheral What is the expected result? Unplug: External Display should be changed to active(b/c it was the previous active) node What happens instead? 3.5 headphone is getting active. Note: Checked with Samus and I see the same behavior.

I don't think that's how device selection works. My understanding is that it will remember the last active device, but once that device is unplugged it will choose the next highest priority. It doesn't keep a list of the last N selected devices. Jenny, am I right? If so I don't think this is a big deal and I'd say WAI unless we get customers who are really bothered by it.

The consistent per device model(starting M51) defines plugging state(active or inactive) based on the previous unplug state of this (plugged now) peripheral, in addition to the priority model. But it does not affect(AFAIK) the state for active node choice when unplugging. So, the priority model should apply, meaning this is working as intended. (prioriy: onboard < display < 3.5 == USB) I guess steps 1. and 2. do not matter here, though at 2. the audio 3.5mm jack is remembered as active. pgangishetty@ you can check with other boards if this is same behavior. No need to reboot or suspend.

I believe this behavior is WAI. |
