Hello, I try to get an ADAU1701 (Sure DAC) running with: - Raspberry Pi Zero Wh - piCorePlayer6.0.0.img *************************************************** Planned system: Logitech Media Server (LMS) Raspberry Pi 4 with piCorePlayer -> LAN -> Router -> WLAN... Speaker right WLAN -> Squeezelite (Raspberry Pi Zero Wh with piCorePlayer) -> i2s -> ADAU1701 (Sure DAC) -> 2 way amplifier -> 2 way speaker Speaker left WLAN -> Squeezelite (Raspberry Pi Zero Wh with piCorePlayer) -> i2s -> ADAU1701 (Sure DAC) -> 2 way amplifier -> 2 way speaker ***************************************************
Following steps I have done to get Squeezelite running with ADAU1701 (Sure DAC) : - Write image to sd card - Copy following files to sd card with windows explorer - wpa_supplicant.conf (with ssid and psk), path pcp_boot/ (to get wlan access to Raspberry Pi Zero Wh) - adau1701-i2s.dtbo, path pcp_boot/overlays/ (adau1701-i2s.dtbo from following source: ...github.com/fvzeppelin/ADAU1701-I2S-Audio-Driver-for-Raspberry-Pi) - Change file content of pcp_boot/config.txt - Search following line and comment with hash: #dtparam=audio=on - Add the following line at the end of the file: dtoverlay=adau1701-i2s After starting Raspberry Pi Squeezelite is not running. Which settings on Squeezelite are necessary? I changed follow Squeezelite settings: (- Audio output device settings: Analog audio (default, no change)) - Output setting: sysdefault:CARD=Output (default: hw:CARD=ALSA) - Max sample rate (-r): 48000 - Upsample setting (-R): vLX After saving, Squeezelite is running. - When LMS sends music to Speaker right, there is sound, but with a lot of noise. - For test, LMS sends to synchronized speaker group with bluetooth speaker and Speaker right, bluetooth speaker has sound with no noise. - Speaker right test with Volumio image and changes for ADAU1701 (Sure DAC): -> Sound with no noise when Volumio is source of sound -> Music with a lot of noise, when Volumio works as Squeezelite player and get sound from LMS. I have no idea to solve the noise problem, could anyone help me, please? ------------------------------------------------------------------------ sound's Profile: http://forums.slimdevices.com/member.php?userid=70285 View this thread: http://forums.slimdevices.com/showthread.php?t=110964
