Description
from Sergey post:
I disabled the onboard sound card and connected USB speakers and USB microphone.
The applet works perfectly.
I have recorded 2 files with a cheap Logitech USB mic.
When I try to use the studio mic "Snowball" I see the same problem in the applet as I see in Audacity: the recorded audio is twice slower and lower in pitch than my voice.
To fix this, Audacity lets you adjust the sampling rate.
I am not the only one who have this problem with Snowball in Linux:

That is sad, because Snowball's sound quality is much better than of any consumer microphones.
I guess Linux will have to fix the bug of incorrect sampling rate detection.
Or we may try to add a manual sampling rate adjustment into the applet like Audacity does.
Or, probably the easiest, record it in Audacity.
I can narrate a book into Audacity and then split it with the Automated Segmentation.
my reply:
I thought of doing this programatically (i.e. letting the system test the audio card until it finds a supported sampling rate), but I guess this is a use-case for letting users override it in a preferences tab.
