You may need to give normal users added privileges. Or it may be that you need to set your running group or user identity to something else in order to use aplay effectively. Could that be the group named audio? See help for the newgrp command. Or just as you have done, try to craft the right sudo command to invoke it the way you want. Then you could add a shorthand to it in sudoers or create a shell alias accordingly.

I am trying to make it work; so here is the update. I tried to experiment with my machine and found that if I plug-out and plug-in the USB sound card again, it is not shown by "aplay -l" command as normal user. But when I do "sudo aplay -l" it lists the USB device. But I am part of "audio" group. "groups" command output: --8<---cut here---start->8--- ankaj@anant:~$ groups pankaj cdrom floppy sudo audio dip video plugdev netdev bluetooth scanner docker --8<---cut here---end--->8--- I don’t know what other configuration is required to list my card using "aplay -l" as a normal user? It lists the card when I reboot the machine. But not when I plug-out and plug-in again. Any hints for this? This could be root cause of my original problem i.e. no sound after sleep and wake-up.
USB sound device present but visible in ‘alsamixer’
I have setup a new system. Apart from the display related issue, that I had posted in another thread, I am facing an issue related to my external ‘Yeti Blue’ sound card. I use it as Mic and Monitor audio. --8<---cut here---start->8--- pankaj@anant:~$ lsb_release -a No LSB modules are available.

Shown as “Blue” S/PDIF input and output devices. But when system wakes up from sleep (suspended), it doesn’t show the devices. However, ‘lsusb’ shows it and ‘/proc/asound/cards’ has an entry. But these devices (mic and speaker) are not taking any input or producing sound. Because they are not visible to Gnome and ‘alsamixer’. --8<---cut here---start->8--- pankaj@anant:~$ lsusb Bus 006 Device 002: ID 2109:0813 VIA Labs, Inc.
