Sample Rate : 44100. Precision : 16 -bit. Duration : 00:00: 11.21 = 494185 samples... File Size : 179k. Bit Rate : 128k. Sample Encoding: MPEG audio ( layer I, II or III) This output gives you a good idea of what codec the audio file is encoded in, the file length, file size, sample rate, and the number of channels.
sound - How to change audio bit depth and sampling rate ...
https://askubuntu.com/questions/138611/how-to-change-audio-bit-depth-and-sampling-rate
To change the sample rate and audio bit depth we need to edit the configuration file for the pulseaudio server /etc/pulse/daemon.conf. Please backup the original settings to restore the defaults in case som settings break your audio. Look for the following entries:; default-sample-format = s16le ; default-sample-rate = 44100

Configuring by ALSA should have got things working, however, if you'd prefer to configure it via PulseAudio, edit /etc/pulse/daemon.conf and make sure the default-sample-rate line reads (ensure it's not commented out with a ';' and the number is correct): default-sample-rate = 48000
Change sampling rate in ALSA - Unix & Linux Stack Exchange
https://unix.stackexchange.com/questions/74558/change-sampling-rate-in-alsa
First copy the "dmixed" pcm, and modify it's hardware section to the desired sample rate and format. Then copy the !default, surround40 and surround51 pcms from it as they are. This will effectively dmix all output and upconvert the sample rate of all 2.0, 4.0 and 5.1 sources to the sample rate that was set in the dmixed pcm.

Configuring Linux ALSA/Pulseaudio for best sound
https://hydrogenaud.io/index.php?topic=94080.0
I don't think ALSA does any samplerate conversion if PulseAudio (or especially Jackd) is being used, as PulseAudio uses direct access to the card but Pulse has a few audio settings that change the sample-rate conversion algorithm, and default sample rate Not in Linux at the moment so bare with me, /etc/pulse/daemon.conf should have settings in it
