MusicLounge do not support I2S audio dac by default but it’s really easy to add the support of such cards.
Example 1 with Hifiberry DAC Plus RCA and Hiffiberry DAC+ PRO on Raspberry PI 4
Example 2 with Hifi Shield 2 (RCA) on Odriod C4
1- HIFIBERRY DAC And Raspberry PI 4
Make sure the board is correctly connected to the PI 4 and to the power supply (5V 3A)
# edit config.txt

Now check if card number is 1 using aplay -l
pi@musiclounge:~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 card 1: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ Pro HiFi pcm512x-hifi-0 [HiFiBerry DAC+ Pro HiFi pcm512x-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0
The trick here is to keep dtparam=audio=on (native headphone) to shift Hifiberry DAC to card number 1 to be dirrectly compatible with MusicLounge audio server settings.
if card number is different go HERE to reconfigure MPD and other audio services
and if you use the alsa equalizer plugin do not forget to change the plughw id in .asoundrc, see the tutorial here
here is a basic setup of the mpd output audio for hifiberry dac
audio_output {
type "alsa"
name "Hifiberry"
device "hw:1,0"
mixer_type "hardware"
mixer_control "Digital"
mixer_device "hw:1"
mixer_index "0"
dop "yes"
}
2- HIFI SHIELD 2 AND ODROID C4
Make sure the board is correctly connected to the C4 and to the power supply ( more info available HERE ).
# Edit /media/boot/config.ini to edit the DTBO settings. Open that file and find the part shown below. The below settings different from the default, it adds a new section named overlay_hifishield (C2) or overlay_hifishield2 (C4) and uses that section by the overlay_profile variable.
@musiclounge:~ $ sudo nano /media/boot/config.ini
For C4 Only:
; Device Tree Overlay overlay_resize=16384 overlay_profile=hifishield2 overlays="spi0 i2c0 i2c1 uart0" [overlay_custom] overlays="i2c0 i2c1" [overlay_hktft32] overlays="hktft32" [overlay_hktft35] overlays="hktft35" [overlay_hifishield2] overlays="hifishield2"
For C2 only:
; Device Tree Overlay overlay_resize=16384 overlay_profile=hifishield overlays="spi0 i2c0 i2c1 uart0" [overlay_custom] overlays="i2c0 i2c1" [overlay_hktft32] overlays="hktft32" [overlay_hktft35] overlays="hktft35" [overlay_hifishield] overlays="hifishield"
Reboot and That’s It!
Now check if card number is 1 using aplay -l
