i'm having this issue on 18.10 as well, 4.18.0-13-generic with a
Logitech C310 (046d:081b). it's been an issue since 18.04 and older for
me; i can't remember when it worked without issue, but it did at some
point.
it appears this commit [0] is the cause as after restoring the specific
USB_QUIRK_RESET_RESUME line for my model and recompiling the kernel i
cannot reproduce the squeaky-voice issue. with the standard kernel i can
reliably reproduce it with Audacity by recording, stopping the
recording, then starting another recording - after ~3 "correct"
recordings the pitch changes.
with the recompiled kernel it appears the device is being "reset" for
each recording:
usb 2-1.6: reset high-speed USB device number 4 using ehci-pci
i do not see this when using the standard 4.18.0-13-generic kernel, so
i'm guessing this is what the quirk does and usb_interface_quirk_list in
quirks.c isn't catching my webcam. i believe there should be a match
based on the code; lsusb output includes the following Interface which
looks like it matches the call (USB_VENDOR_AND_INTERFACE_INFO(0x046d,
USB_CLASS_VIDEO, 1, 0)) since USB_CLASS_VIDEO is 0x0e which matches the
bInterfaceClass, and subclass/protocol also match. note that this is not
the first interface in the lsusb output, not sure if that matters.

Logitech camera microphone does not work / makes "chipmunk" sound

Bug description:
Did not know which application to log so feel free to let me know and
I'll upload the correct log. In Natty, this mic worked great. Now,
in the sound control panel, the mic does not show any input level at
all and sound recorder does not record any sound.
edit: I can also confirm the same behavior as Alex Popovskiy. It
either works but plays too fast (high pitch) or it doesn't work at
all.
