There are three jack events for a sound card on a desktop computer,
namely Speaker, Headphone, and Desktop Speaker. When both audio
devices are available, users cannot distinguish which audio device
is being used. Can we consider adding Line Out? similar to the HDA
sound card. This can change one of them and reduce the complexity
of the upper layer adaptation of the sound card.

Is 0x0308 something properly defined standard?  
If so, we can add the entry, of course.


thanks,

Takashi

Sorry, this is not a new standard. It's just my personal idea. Can we 
promote

the addition of this, adding this Line Out, so that it can be similar to 
hda,

simplifying the adaptation task of the core outer layer? The jack events

are relatively unified. Otherwise, for the current sound card, the

rear jack event is Speaker, which requires separate adaptation.

Well, the question is how this 0x0308 came up.
It's the value that is used actually by the descriptor, right?
That is, the vendor uses this non-standard number regularly?
If so, we may define it as a de facto standard and implement as you
suggested.

Basically I like the idea, but I'd like to know more about the current
situation at first.


thanks,

Takashi

Could you show us alsa-info.sh output? It looks that this hardware may require 
a custom UCM configuration.

As you mentioned, the current UCM configuration has not been carried out 
yet.

The current alsa information is after updating the firmware, and the 
Speaker has been replaced with Line.


 From the picture, we can see that currently we have three jack events, 
namely "Headphone Jack", "Speaker Jack",

and "Desktop Speaker Jack". We are currently considering replacing 
"Speaker" with "Line Out". Afterwards,

we will proceed with the UCM configuration to ensure it works properly.


get_connector_control_name()
-       if (is_input)
-               strlcat(name, " - Input Jack", name_size);
-       else
-               strlcat(name, " - Output Jack", name_size);
+       strlcat(name, " Jack", name_size);


We have made modifications to this function, so when adapting to HDA or 
USB sound cards,

we believe it can reduce the workload in the sound card adaptation task. 
Referring to HDA sound cards,

the rear headphone jack is usually labeled "Line Out". Therefore, adding 
this enumeration here would be beneficial.

Is it feasible to add a Line Out?
The original intention was to reduce the complexity of upper level UCM 
adaptation and make the USB onboard sound card backend consistent with HDA.

New Intel HDA hardware is using the SOF driver for which UCM is mandatory. 
It's easy to add new entry to UCM configs.
