Description

Alsa report log: https://pastebin.com/M3zCP6V8

Description of problem: My usb mic won't work, infact when I try the record test, #(arecord -f S16_LE -r 16000 -D your_input_device test.wav) I get:

"ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM your_input_device
arecord: main:788: audio open error: No such file or directory"

Furthermore I get a lot of ALSA errors when I check for the AlexaPi status:

Research direction
The issue reports ALSA errors and 'Unknown PCM your input device'. The fix likely involves configuring the correct audio input device in AlexaPi's settings or ALSA configuration files. Check the AlexaPi configuration file for the audio input parameter and verify that the USB mic is recognized by ALSA. Review existing comments for any suggested solutions or similar past issues.
