Now USB mic Samson Direct Go(tested with 2 Samson devices and 2 TX2 dev boards) records with overload(like vocoder) sound.
I have tried arecord, audacity, pulseaudio, alsa but always broken sound.
On JetPAck 3.3 was excellent recording.

Also, fps for gstreamer pipeline is wrong.
File was recorded, but it has higher speed of playback. It looks like that appsrc syncing with alsasrc.
Without alsasrc or with other mic all is ok.
Target fps is 30f/s. But now, with Samson Mic alsasrc, fps is about 40f/s on JetPack 4.2.
If target fps is 25f/s with Samson Mic alsasrc, then final fps is about 33f/s
Have tried another china CD04 mic and all is fine - fps and voice.
I have tested a USB headset with L4T rel32.1 (version of L4T in Jetpack 4.2) and did not observe any isssues, but obviously this is a different USB device and from what you have said that issue appears to be specific to the Samson Mic.
For testing capture on the USB Mic, I selected the USB Mic under the Ubuntu desktop ‘Sound’ settings and executed the command …
$ arecord -r 48000 -f S16_LE -c 1 -d 10 cap.wav
Is this the same way that you tested the Samson Mic with arecord? Playing back the file with aplay sounds fine.
Have you dumped all the mixer settings for the Samson Mic and compared with the earlier release …
$ amixer -c <soundcardname>
Note that soundcard name is listed under /proc/asound/cards.
Can you also confirm the jetson power-model setting by executing …
$ sudo nvpmodel -q
NV Power Mode: MAXP_CORE_ARM

I do wonder if this could be related to the problem because this is not seem good …
I do not see this on my setup. Do you always see this with the Samson Mic? Do you see this with the Mic that works?
I am not sure about why the gstreamer fps would be off and I would need someone to check on this.
Hi,
Could you try below combinations?
1 Samson + jetpack4.2 + other wireless mouse( such as Logitech )
2 Other USB mic + jetpack4.2 + BOW wireless mouse
