Modifying alsamixer volume has no effect #5

I followed all steps, and nearly everything works flawlessly. I was able to achieve the end goal - adding the local URL as a radio station in Sonos. I can now play music from my turntable through Sonos by way of: turnable > Behringer UFO202 > Raspberry Pi Model 3 B+ > WiFi to LAN.

All of that being said, I have to turn the Sonos volume very high relative to other Sonos sources (Spotify, regular TuneIn radio stations, Sonos Radio, etc.). So I have tried to follow the alsamixer advice at the end of step 4 to no avail.

I can run alsamixer, and I can use F6 to switch to card USB Audio CODEC, and I can freely raise and lower the volume of any of the sound cards in alsamixer (bcm2835 Headphones, USB Audio CODEC, and vc4-hdmi), but the modifications to the volume have no effect on the turntable stream. The volume is static, even if I dial it down to 0.

Is the issue that of the three cards available in alsamixer, none of them is a card representing the USB turntable?

Update: I missed the part about hitting TAB to modify boost. When I hit TAB, it then selects Boost, but Boost is written in red text, and the arrow keys and +/- keys have no effect. Boost is locked at 20. I can only use arrow keys and +/- for PCM/Playback, which has no effect at all.

I do have the same issue. Did you find any solution to this?
