Hello, I'm using 2 codecs (tlv320aic3x-codec) each which both are registered into same sound card, each as a single device. After boot I have the following devices: root@dm814x:~# cat /proc/asound/devices 0: [ 0] : control 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback 24: [ 0- 0]: digital audio capture 25: [ 0- 1]: digital audio capture But I get the following error messeges during boot: usbcore: registered new interface driver snd-usb-audio Registered tvp5158 audio codec PM: Adding info for platform:soc-audio.0 PM: Adding info for No Bus:TLV320AIC3X_2 asoc: tlv320aic3x-hifi <-> davinci-mcasp.2 mapping ok snd_soc_instantiate_card 7 tlv320aic3x-codec 2-0019: tlv320aic3x-codec.2-0019: Failed to add PCM Playback Volume: -16 asoc: failed to add dapm kcontrol Right HPCOM Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Left HPCOM Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Right HP Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Left HP Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Mono Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Right Line Mixer Line2L Bypass Switch: -16 asoc: failed to add dapm kcontrol Left Line Mixer Line2L Bypass Switch: -16 asoc: failed to add kcontrol Right Line2R Mux asoc: failed to add kcontrol Right Line1R Mux asoc: failed to add kcontrol Right Line1L Mux asoc: failed to add dapm kcontrol Right PGA Mixer Line1R Switch: -16 asoc: failed to add kcontrol Left Line2L Mux asoc: failed to add kcontrol Left Line1R Mux asoc: failed to add kcontrol Left Line1L Mux asoc: failed to add dapm kcontrol Left PGA Mixer Line1L Switch: -16 asoc: failed to add kcontrol Right HPCOM Mux asoc: failed to add kcontrol Right DAC Mux asoc: failed to add kcontrol Left HPCOM Mux asoc: failed to add kcontrol Left DAC Mux PM: Adding info for No Bus:TLV320AIC3X_3 asoc: tlv320aic3x-hifi <-> davinci-mcasp.3 mapping ok PM: Adding info for No Bus:card0 PM: Adding info for No Bus:pcmC0D1p PM: Adding info for No Bus:pcmC0D1c PM: Adding info for No Bus:pcmC0D0p PM: Adding info for No Bus:pcmC0D0c PM: Adding info for No Bus:controlC0 ALSA device list: #0: TI81XX SOUND0 What is the reason for the "asoc: failed to add dapm kcontrol" and the " 'control ... already present" messeges ? Is it becuase both codec are registered on same card (single card) ? If I move each to be registered to its own card will it resolve this issue ?
