OExternal and internal sound devices with 4.20

[Oldjoeclarke]

Hi,
as a long time frustrated windows user I took the chance to enter the linux world when I came across an ancient Dell Latitude CPt 500 laptop (128 MB ram, maestro3 sound): Idecided to try to make it the mp3 and webradio player at home. Though I had to search this great forum a bit, installing Puppy Linux was easy and the performance is very impressive.

But when tried to improve the sound quality by installing a Behringer UCA 202 external usb sound device things started to become complicated for me. Though the 202 obviously is recognized by the system I cannot make it the default sound device.

The ALSA wizard says "Override USB audio" and whatever I try to modify the modprobe.conf to blacklist the onboard sound or to rename the devices, after every reboot I find something like

alias snd-card-0 snd-maestro3
alias sound-slot-0 snd-maestro3
alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-usb-audio


in it. I think that means even if I would get the usb audio to work, the system would prefer the internal soundcard.

I really could need a little help with this...

Thank you so much,
