Install Raspotify for Sportify

One of the 2021 project is to enhance the audio quality of playing sportify.

1. Installation of respotify software

2. config the /etc/asound.conf

Install of respotify is easy:

reference site: https://dtcooper.github.io/raspotify/

Command: curl -sL https://dtcooper.github.io/raspotify/install.sh | sh

Then you need to config the /etc/asound.conf file in order to control the output of the sportify. Even you config the output to HDMI instead of the headphone.

Create the file: /etc/asound.conf

Paste the following code:

# /etc/asound.conf

###############################################################################

# Find your sound card:
# aplay -l

# Find your card's supported format(s) and sampling rate(s) While no other audio is being played:
# aplay -Dhw:<card #>,<device #> --dump-hw-params /usr/share/sounds/alsa/Front_Right.wav
# For example:
# aplay -Dhw:0,0 --dump-hw-params /usr/share/sounds/alsa/Front_Right.wav

# The output should look something like this if the card and device combination is correct:

# ACCESS:  MMAP_INTERLEAVED RW_INTERLEAVED
# FORMAT:  S16_LE S24_LE S32_LE
# SUBFORMAT:  STD
# SAMPLE_BITS: [16 32]
# FRAME_BITS: [32 64]
# CHANNELS: 2
# RATE: [8000 192000]
# ...

# The above card supports formats S16_LE, S24_LE, and S32_LE, at up to a sampling rate of 192000.

# Uncomment and replace with the sampling rate of your choice.
# defaults.pcm.dmix.rate 48000

# Uncomment and replace with the format of your choice.
# defaults.pcm.dmix.format S16_LE 

# Change to the card number or name that you want to be the default control card.
# Default: 0
defaults.ctl.card 1

# Change to the card number or name that you want to be the default playback card.
# It should usually be the same as defaults.ctl.card.
# Default: 0
defaults.pcm.card 1

# Change to the device number that you want to be the default device on the default card.
# 0 or 1 is usually the correct device number.
# Default: 0
defaults.pcm.device 0

# Change to the subdevice number that you want to be the default subdevice on the default device.
# Should rarely need to be changed.
# Default: -1
defaults.pcm.subdevice -1

# To install high quality samplerate converters on Debian based systems:
# sudo apt install -y --no-install-recommends libasound2-plugins 

# To list available rate_converter's:
# echo "$(ls /usr/lib/*/alsa-lib | grep "libasound_module_rate_")" | sed -e "s/^libasound_module_rate_//" -e "s/.so$//"

# Uncomment and replace speexrate_medium with the rate_converter of your choice.
# defaults.pcm.rate_converter speexrate_medium

# Once everything is configure close and save this file and test with:
# speaker-test -c2 -l1

# While audio is playing you can verify your settings with:
# cat /proc/asound/card*/pcm*p/sub*/hw_params

I use the default card : card 1 simply because my pi's headphone is card 1:

pi@raspberrypi:~ $ aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: b1 [bcm2835 HDMI 1], device 0: bcm2835 HDMI 1 [bcm2835 HDMI 1]

Subdevices: 3/4

Subdevice #0: subdevice #0

Subdevice #1: subdevice #1

Subdevice #2: subdevice #2

Subdevice #3: subdevice #3

card 1: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones]

Subdevices: 4/4

Subdevice #0: subdevice #0

Subdevice #1: subdevice #1

Subdevice #2: subdevice #2

Subdevice #3: subdevice #3

Then you need to restart the respotify

sudo service raspotify restart

This should be it. Once I have my HIFIberry arrive. I will post the setup with my DAC and Headphone AMP for the final setup.
