How do I tell winetricks to work with a different prefix?

I'm trying to enable alsa on different prefix than default through winetricks. More specifically, the prefix that has Rosetta Stone on it, as it cannot see my microphone.

When I open winetricks, it only lets me select default. I tried anyway, on default, and it did not resolve the issue.

I saw some answers online, through the terminal, but that didn't work either. Maybe I have the syntax wrong?

steve@stevelap:~$ WINEPREFIX=~/.PlayOnLinux/wineprefix/Rosetta sh winetricks alsa
sh: 0: Can't open winetricks
steve@stevelap:~$ sudo WINEPREFIX=~/.PlayOnLinux/wineprefix/Rosetta sh winetricks alsa
[sudo] password for steve: 
sh: 0: Can't open winetricks

Could anyone please offer assistance? Thanks!

Solution 1:

I found the answer to my question.

The following worked for me:

WINEPREFIX=/home/steve/.PlayOnLinux/wineprefix/Rosetta winetricks

It launched the GUI, and when I selected default then clicked browse files, it brought me to the Rosetta prefix to confirm.
