Hi
While sound work out of the box (with headphone switching) on the 1-2 year
older Latitude 7270, it does not on my new machine.
The internal speaker works fine. If I plug in external speakers in the
headphone jack, sound still goes to the internal speaker while a very load
buzz comes from the external speakers.
Do we have a solution for this?
I do not believe we have anything that detects stuff plugged into
and removed from the newer sound stuff that needs switching to
change from internal to external speakers.
I think you need to do what I have to do when I plug in external
speakers on my thinkpad x230:
sysctl hw.snd.default_unit=1
And when I unplug them I have to do:
sysctl hw.snd.default_unit=0
to switch back to the internal speakers.
Hi Rod,
Can you post the output of 'sysctl dev.pcm' and 'sysctl dev.hdaa'
