Speaker sound after copying SD card

[MilkShake]

Hi,
Can someone help troubleshoot my sound settings on my RPI4 with Raspbian OS? I use the MMM-Sounds module to trigger sounds at different events, but since copying the SD card to a new one, it seems to have lost the ability to play wav files. Cannot remember how I used to set it up!

When i do Aplay sound.wav nothing happens it plays the wav with no sound.

When I do aplay -l:

card 2: Device [USB2.0 Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

When I do:

speaker-test -c2 -twav -l7 -D plughw:2,0

the speaker outputs front left…front right…front left…etc. so I know it is working.

Thanks a lot for the help!

@MilkShake try
aplay -D plughw:2,0 xxx.wav

If you make an ~/.asoundrc
You should be able to set the default output device
Notice the . In front
