I think you're suffering the same problem I am with my Echo Layla 3G. Does
'echomixer' work?
For some time now I have been running with commit 275353bb6 (copied below)
reverted.
I did my most recent tests on kernel 4.10.3, resulting in the revert of
that commit. I with the reverted commit. I recall that alsactl, alsamier
were also affected.
I have been intending to make a 'proper' report to the list, or even
investigate more myself. But priorities did not permit that yet. I also
wasn't able to find information on what these fields actually mean. As far
as I could tell, some of these attributes are unique to the echo3g and
echomixer.
Thanks

Subject: [PATCH] ALSA: echoaudio: purge contradictions between dimension
matrix members and total number of members
Currently, sound device drivers for PCI cards produced by Echo Audio
support dimension parameter of element information. But the information
has contradictions to the number of members of each element. I guess that
this comes from the assumption that these sound cards are used only by
'echomixer' in userspace. But ideally, they should be used with usual ALSA
control applications.
This commit removes the contradiction. As a result, 'Monitor Mixer Volume'
and 'VMixer Volume' elements are shown in usual ALSA control applications
such as 'amixer' and 'alsamixer' in series.
