So I'm good with Linux, but hardware isn't my strong suit.
I have a USB speaker that I've plugged into my machine, but I can't figure out how to configure Linux to use it.
I see it loaded in /var/log/messages

Based on that last line, I see these files have appeared:

I have modules installed:
snd_seq_oss
snd_seq_midi_event
snd_pcm_oss
snd_mixer_oss
snd_usb_audio
snd_usbmidi_lib
snd_rawmidi
snd_seq_dummy
snd_seq

snd_hda_codec_generic
snd_hda_intel
snd_hda_codec
snd_hda_core
snd_hwdep
snd_pcm
snd_timer
snd
soundcore
But every time I run alsamixer , I only see the built-in sound card:
┌───── Sound Card ──────┐
│- (default) │
│0 HDA Intel PCH │
│ enter device name...│
└───────────────────────┘
and it's not listed in /proc/asound/cards
% cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xb1228000 irq 128
What am I missing?

I suspect I found my problem. The computer thinks it's a keyboard.
