Hi guys,
I’ve been having a problem with audio for a while now, sometimes it works other times it seems to be the cipman, I can’t figure out what it depends on, whether it’s caused by some incompatible audio dependency or some open programs that make the audio do this effect.
I would like to remove it and get back to normal.
Thanks to those who can help me out.
under the pci and usb list, if it can be helpful

in the tests i’ve done sometimes this effect disappears quicker and a few octaves higher, returning to normal; but then if i redo the same procedure after restarting the PC it comes back and even redoing the same things that had allowed me to remove the Chipmunks effect, so i don’t know what it’s due to.
I’m a regular user and volunteer like most others around here. I’ve not heard of this unwanted ‘chipmunk’ sound before. It is always useful to get defintive information about a user’s hardware environment in these sorts of situations. Graphics and audio (hardware/connections) might both play a part here…
Reading the post unlike the linuxmint user the problem I have is only when recording, and from the tests done sometimes it disappears if I exit VirtualBox other times even if it is not active it doesn’t work and records me faster and a few octaves higher like Alvin.
Of course my microphone is the logitech camera, and I have the problem especially in video calls like skype or with OBS Studio
Ok, your opening post was vague, nothing mentioned about recording…so left to speculate.
Try investigating the sample rate settings. The linuxmusicians forum might be of further help here. Once such thread: https://linuxmusicians.com/viewtopic.php?t=25768
The opening post included a potentially useful link:
The topic describes creating a user ~/.asoundrc file, with entries to set the recording sample rate at 16kHz. (I’ve adjusted to use your product ID):
pcm.usb
{
type hw
card U0x46d0x81b
}
pcm.!default
{
type asym
capture.pcm
{
type plug
slave.pcm "usb"
rate 16000
}
}
Once done, save the custom config, and you may need to replug the web cam and restart any recording app you may be using. Then try testing the webcam mic again.
By dint of trying, I figured out what is causing my microphone to do the “Alvin super star” effect.
Basically it is VirtualBox, when I launch windows XP virtualized and launch a very old graphics program, inside WIN-XP, that has to read a USB aladin key, in order to launch the program itself, at that point when I register it gives this disturbance.
Probably the usb of the flash drive and the usb of the webcam conflict with each other, previously even with version 15.2 I never had this problem because, XP I was using it with a real PC then it broke down so I virtualized it.
I should add that the same virtualization with linuxmint does not give me the same problem, but there the microphone is not in usb because it is a laptop and not a fixed pc as in this case.
Now I just have to figure out how to make sure I don’t have the two usb’s in conflict .
Correction, actually today the problem occurred to me again when I did a test recording with OBS studio. then I launched Telegram and tried to record, there were no other applications open, not even VirtualBox. on the pc I couldn’t hear myself, and then I listened to the audio on the smatphone which was perfect and not sped up. whereupon I relaunched OBS studio and the audio was right there too. I can’t figure out if something is changing some parameter which then gets recorrected with Telegram in this case.
I’ve tried, but it doesn’t work, there’s something disturbing the usb and it’s restored to correct operation, sometimes not always, using a second programme such as telegram, but I don’t know what changes to make it work properly
Seen your audio settings, which reminded me on an audio configuration issue at my end, which got solved via this fantastic info here:
My other Audio issue had been Firefox breaking the audio on playing videos, which I was able to fix via uninstalling the older YaST Firefox and installing the newer Flatpak Firefox via Software.
