I faced a problem (Debian 11) with incorrect sample format used for my microphone (webcam) which brings high speech rate at any voice chats.

With arecord I used format s16_le and that record had normal speed of speech. I used ~/.asoundrc file contains

pcm.!microphone {
    type hw
    ipc_key 4096
    ipc_perm 0666 
    slave.pcm "hw:0,0" #found webcam via arecord -l
    slave 
    {
        channels 1
        format S16_LE
    }
}

when I restarted audio system with

pulseaudio -k

and checked via Skype I had normal voice record but the next tries brought high speed speech back.

Also I have no idea how to use ipc_key and ipc_perm correctly.

I have tried to uncomment a line default-sample-format = s16le in the file /etc/pulse/demon.conf It made no differences.

I have checked many (tons) resources but all of them had no solution to me. I hope to find here anyone who knows how to deal with such problem.
