Revision 29664923725a384dc7e0f74af7c66e5ab7bb2a26 authored by Marco Giunta on 18 October 2021, 16:25:52 UTC, committed by Takashi Iwai on 19 October 2021, 06:07:01 UTC
When a Jieli Technology USB Webcam is connected, the video part works well, but the mic sound is speeded up. On dmesg there are messages about different rates from the runtime rates, warnings about volume resolution and lastly, the log is filled, every 5 seconds, with retire_capture_urb error messages. The mic works only when ep packet size is set to wMaxPacketSize (normal sound and no more retire_capture_urb error messages). Skipping reading sample rate, fixes the messages about different rates and forcing a volume resolution, fixes warnings about volume range. I have arbitrarily choosed the value (16): I read in a comment that there should be no more than 255 levels, so 4096 (max volume) / 16 = 0-255.
