https://bugzilla.kernel.org/show_bug.cgi?id=218544 --- Comment #11 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- The most obvious difference is that the "good" device requires only 85 us/frame for its audio-in channel whereas the "bad" device requires 234 us/frame. This is the difference between 16-bit and 24-bit captures that you mentioned originally. (The 39 vs. 24 for the interrupt endpoint wouldn't have a significant effect.) There could be other factors in play, but that difference is likely enough to tip the balance. The times in the bandwidth file indicate that audio subsystem is using the device's higher bandwidth setting. Using the lower bandwidth setting instead could well make a difference. I don't know how to tell the sound interface to do this; maybe Takashi can say. -- You may reply to this email to add a comment.
