I was looking at an old question that gave advice for fixing these errors:

It said to do the following for my default bluetooth device:
$ cat ~/.asoundrc
defaults.bluealsa.interface "hci0"
defaults.bluealsa.device "XX:XX:XX:XX:XX:XX"
defaults.bluealsa.profile "a2dp"
defaults.bluealsa.delay 10000
The problem is, I'm not using any Bluetooth devices. I have a USB mic plugged in I'm trying to use. I put in some dummy information, but now I'm getting the following errors:
Expression 'alsa_snd_pcm_hw_params_set_period_size_near( pcm, hwParams, &alsaPeriodFrames, &dir )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 924
ALSA lib bluealsa-pcm.c:649:(_snd_pcm_bluealsa_open) Invalid BT device address: XX:XX:XX:XX:XX:XX

Is there any way to simply tell pyaudio I don't want to use any Bluetooth?
I'm sorry if this is not the proper way to ask this followup question but it said I didn't have enough reputation to post a comment.
My program runs fine but I'd like to get rid of the error/warning messages since it makes finding my output more cumbersome.
Thanks so much.
