I'm not sure why it's not able to detect the audio formats for your USB device. Try also-capabilities --help.
alsa-capabilities --help give just the help of the command
Code: pi@moode-pt:~ $ alsa-capabilities -h
Usage:
alsa-capabilities [ -l a|d|u ] [ -c <filter> ] [-a <hwaddress>] [-s] [ -q ]
Displays a list of each alsa audio output with its details
including its hardware address (eg. `hw:x,y').
The list may be limited by applying one or more options with
arguments, for the type of output (`-l' or `--limit'), the name of
the card and/or output (`-c' or `--customfilter'), and/or the
hardware address (`-a\ or `--address').
The `-s' or `--samplerates' switch turns on the detection and
display of the supported samplerates per encoding format for each
output.
-l TYPEFILTER, --limit TYPEFILTER
Limit the interfaces to TYPEFILTER. Can be one of
`a' (or `analog'), `d' (or `digital'), `u'
(or `usb'), the latter for USB Audio Class (UAC1
or UAC2) devices.
-c REGEXP, --customlimit REGEXP
Limit the available interfaces further to match
`REGEXP'.
-a HWADDRESS, --address HWADDRESS
Limit the returned interface further to the one
specified with HWADDRESS, eg. `hw:0,1'
-s, --samplerates Adds a listing of the supported sample rates for
each format an interface supports.
-q, --quiet Surpress listing each interface with its details,
ie. only store the details of each card in the
appropriate arrays.
-j, --json Surpress normal output but create json formatted
output instead.
-n, --nocolor Supresses colorized output.
-h, --help Show this help message

You might want to post the -s output in the maintainers Git repo or project site to see if he can look into it. There are some links at the end if the --help.

Let's review the bidding.
- You note an anomaly regarding missing information
- Tim tells you how to check the third-party software component that's supposed to supply the information.
- Your check confirms the third-party software component is not returning the information.
- Rather than report this problem to the maintainer of the third-party software component as Tim suggested, you throw shade at Tim.
Isn't that special.

Isn't that special my dear old friend, it would be a better approach to assume that you made some mistakes instead of suggesting the solution of the reported problem to be postponed to third parties
here you can find what GentooPlayer can get from the Khadas Tone Board dac itself, so maybe not a problem to be attributed to ALSA

What Linux command generated that output?

The last has a link to the source code... license seems fine
Seems to install and work ok on my Linux desktop... needed to install 'libasound2-dev' for it to compile.

Will try on MoOde and report.
RE: Khadas Tone Board - Tim Curtis - 02-08-2020
Cool, thanks Bob :-)
I'll have a look.
RE: Khadas Tone Board - DRONE7 - 02-08-2020
Hmmm... my limited linux skills hit a snag...
compiled but cannot run...
errors...
Code: sudo make install
install -D -m 755 alsacap /usr/local/bin/alsacap
install -D -m 644 alsacap.1 /usr/local/share/man/man1/alsacap.1
$ alsacap
-bash: /usr/local/bin/alsacap: cannot execute binary file: Exec format error
The error seems to refer to an x86 binary being run on arm ???
RE: Khadas Tone Board - Tim Curtis - 02-08-2020
No worries.
The procedure below worked perfectly for me
Code: wget https://github.com/bubbapizza/alsacap/archive/master.zip
sudo unzip -q ./master.zip
sudo rm ./master.zip
cd ./alsacap-master
sudo ./bootstrap
sudo ./configure
sudp make
sudo make dist
///////////////////////////////
sudo cp alsacap-1.0.tar.gz ~/
cd ~/
sudo tar xfz ./alsacap-1.0.tar.gz
cd alsacap-1.0
sudo ./configure
sudo make
I didn't run make install cos no need for the man page. The binary is ./alsacap-1.0/src/alsacap
This can be copied to /usr/local/bin and given +x permission
It was trivial to replace alsa-capabilities with alsacap in moOde. Now we get formats for USB Audio devices :-)
Thx again Bob!
