Re: Inserting headphone "locks" audio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


I have two drop-downs, both titled "Built-in Audio"  The top is "Digital Stereo (HDMI) Output" and the other is "Analog Stereo Duplex"

I'm not clear on what I would change.  The top one has a bunch of other options, all of which are unplugged and unavailable.  The other has three more options... "Analog Stereo Input", "Analog Stereo Output", and "Off"

Some audio interfaces have the HDMI and the analog ports exposed as
different profiles of the same card. If you run pavucontrol and go into
the Configuration tab, check what is listed in the Profile drop-down for
your audio card. The profile that corresponds to using only the analog
ports is usually called "Analog Stereo Duplex". The HDMI options (if
present) will have various names depending on the number of ports and
which channel configurations your card supports.

Changing the selection in that dropdown should live re-route any playing
audio to the selected port. Try selecting some of the HDMI options and
see if that gets the audio routed the way you want.
