How to output sound from phone through laptop speakers

cracauer@ said:
The adapter costs less than 10 bucks.

Problem is that many laptops only have mono analog in.

given that 99% of all laptop speakers are crap anyways, I guess that's a non-issue...

You can also get USB-Aux/Line-in DACs/adapters for less than 5$, I guess they still offer way higher resolution than any laptop squeaker can reproduce.
I saw they are even available as USB-C-to-USB-C, so this seems to be the easiest solution (given that android isn't broken in some way regarding usb audio output)
 
I attached a C-Media Electronics, Inc. CM108 Audio Controller, but not sure if if needs any drivers or how to use it.

Anyone know?

I have a few usb audio here using freebsd. Usb audio works by default. Nothing special needed.

I would say , just plug it in and check "dmesg". If you see nothing ... then its not true USB-AUDIO....

I tried that but it doesn't work.

I probably need to install something.

No, but you need to make a "connection" (for lack of a better description from your input device (often they show up as record channels) to your output device (often labeled as playback channels.
How yo do that with a gui thing I don't know. If you use Pulseaudio you can use the pactl command for this
Code: 
tingo@kg-core2:~ $ pactl-h
sh: pactl-h: not found
tingo@kg-core2:~ $ pactl help
pactl [options] stat
pactl [options] info
pactl [options] list [short] [TYPE]
pactl [options] exit
pactl [options] upload-sample FILENAME [NAME]
pactl [options] play-sample  NAME [SINK]
pactl [options] remove-sample  NAME
pactl [options] load-module  NAME [ARGS ...]
pactl [options] unload-module  NAME|#N
pactl [options] move-(sink-input|source-output) #N SINK|SOURCE
pactl [options] suspend-(sink|source) NAME|#N 1|0
pactl [options] set-card-profile  CARD PROFILE
pactl [options] get-default-(sink|source)
pactl [options] set-default-(sink|source) NAME
pactl [options] set-(sink|source)-port NAME|#N PORT
pactl [options] get-(sink|source)-volume NAME|#N
pactl [options] get-(sink|source)-mute NAME|#N
pactl [options] set-(sink|source)-volume NAME|#N VOLUME [VOLUME ...]
pactl [options] set-(sink-input|source-output)-volume #N VOLUME [VOLUME ...]
pactl [options] set-(sink|source)-mute NAME|#N 1|0|toggle
pactl [options] set-(sink-input|source-output)-mute #N 1|0|toggle
pactl [options] set-sink-formats #N FORMATS
pactl [options] set-port-latency-offset CARD-NAME|CARD-#N PORT OFFSET
pactl [options] send-message RECIPIENT MESSAGE [MESSAGE_PARAMETERS]
pactl [options] subscribe

The special names @DEFAULT_SINK@, @DEFAULT_SOURCE@ and @DEFAULT_MONITOR@
can be used to specify the default sink, source and monitor.

pipewire has simliar commands as well (but I don't use it, so I don't know how they work)
