nate451 Posted April 25, 2020 Share Posted April 25, 2020 PROBLEM: After setting up my Piano 2.1, I get sound out of my subwoofer in Dual-Stereo, Dual-Mono, or Subwoofer 2.0 modes, but no sound out of my L or R analog outputs under any circumstances.DETAILS: I have a Piano 2.1, and I have its dtoverlay enabled in /boot/config.txt. I also have the system audio turned off with dtparam=audio=off. I get this output from aplay -l: **** List of PLAYBACK Hardware Devices **** card 0: PianoDACPlus [PianoDACPlus], device 0: PianoDACPlus multicodec-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 When I play audio using aplay, mplayer, or even speaker-test, I only get output from my subwoofer. I've tried two different speakers on the regular analog outputs, neither with any result, then confirmed that they were working by connecting them to a hifiberry on a separate raspberry pi. Here's the output of my amixer, in case it's helpful: Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 207 Mono: Front Left: Playback 165 [80%] [-21.00dB] [off] Front Right: Playback 165 [80%] [-21.00dB] [off] Simple mixer control 'DSP Program',0 Capabilities: enum Items: 'FIR interpolation with de-emphasis' 'Low latency IIR with de-emphasis' 'High attenuation with de-emphasis' 'Fixed process flow' 'Ringing-less low latency FIR' Item0: 'FIR interpolation with de-emphasis' Simple mixer control 'Analogue',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 1 Mono: Front Left: Playback 1 [100%] [0.00dB] Front Right: Playback 1 [100%] [0.00dB] Simple mixer control 'Analogue Playback Boost',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 1 Front Left: 0 [0%] [0.00dB] Front Right: 0 [0%] [0.00dB] Simple mixer control 'Auto Mute',0 Capabilities: pswitch Playback channels: Front Left - Front Right Mono: Front Left: Playback [on] Front Right: Playback [on] Simple mixer control 'Auto Mute Mono',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'Auto Mute Time Left',0 Capabilities: enum Items: '21ms' '106ms' '213ms' '533ms' '1.07s' '2.13s' '5.33s' '10.66s' Item0: '21ms' Simple mixer control 'Auto Mute Time Right',0 Capabilities: enum Items: '21ms' '106ms' '213ms' '533ms' '1.07s' '2.13s' '5.33s' '10.66s' Item0: '21ms' Simple mixer control 'Clock Missing Period',0 Capabilities: enum Items: '1s' '2s' '3s' '4s' '5s' '6s' '7s' '8s' Item0: '2s' Simple mixer control 'Deemphasis',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'Digital',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 207 Mono: Front Left: Playback 165 [80%] [-21.00dB] [on] Front Right: Playback 165 [80%] [-21.00dB] [on] Simple mixer control 'Dual Mode',0 Capabilities: enum Items: 'None' 'Dual-Mono' 'Dual-Stereo' Item0: 'Dual-Stereo' Simple mixer control 'Lowpass',0 Capabilities: enum Items: '60' '70' '80' '90' '100' '110' '120' '130' '140' '150' '160' '170' '180' '190' '200' Item0: '60' Simple mixer control 'Max Overclock DAC',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 40 Mono: 0 [0%] Simple mixer control 'Max Overclock DSP',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 40 Mono: 0 [0%] Simple mixer control 'Max Overclock PLL',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 20 Mono: 0 [0%] Simple mixer control 'Subwoofer',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 207 Mono: Front Left: Playback 165 [80%] [-21.00dB] [off] Front Right: Playback 165 [80%] [-21.00dB] [off] Simple mixer control 'Subwoofer mode',0 Capabilities: enum Items: 'None' '2.0' '2.1' '2.2' Item0: 'None' Simple mixer control 'Volume Ramp Down Emergency Rate',0 Capabilities: enum Items: '1 sample/update' '2 samples/update' '4 samples/update' 'Immediate' Item0: '1 sample/update' Simple mixer control 'Volume Ramp Down Emergency Step',0 Capabilities: enum Items: '4dB/step' '2dB/step' '1dB/step' '0.5dB/step' Item0: '4dB/step' Simple mixer control 'Volume Ramp Down Rate',0 Capabilities: enum Items: '1 sample/update' '2 samples/update' '4 samples/update' 'Immediate' Item0: '1 sample/update' Simple mixer control 'Volume Ramp Down Step',0 Capabilities: enum Items: '4dB/step' '2dB/step' '1dB/step' '0.5dB/step' Item0: '1dB/step' Simple mixer control 'Volume Ramp Up Rate',0 Capabilities: enum Items: '1 sample/update' '2 samples/update' '4 samples/update' 'Immediate' Item0: '1 sample/update' Simple mixer control 'Volume Ramp Up Step',0 Capabilities: enum Items: '4dB/step' '2dB/step' '1dB/step' '0.5dB/step' Item0: '1dB/step' Do you have any idea what might be happening?

RAH905 Posted April 10, 2022 Share Posted April 10, 2022 I too ran into this infamous Piano2.1DAC with no sound. OS sees the soundcard. However, there are no types of sound output. (i'm done pulling my hair out) Pretty expensive piece of PCB board. Link to comment
