Re: [Alsa-user] Bower's & Wilkins PX headphone - snd-usb-audio error
Thanks for your help. I tested now various samplerates. Working: 48000 Hz, 96000 Hz, 192000 Hz Not working: 44100 Hz, 22050 Hz, 16000 Hz, 8000 Hz "Not working" means that aplay doesn't complain, but I can't hear anything. Hope that helps; if you guys need any additional tests, please let me know.

So it seems that the new firmware is incompatible and works without the quirk. We need to sort it out. Erik, do you have your device still with the old firmware? If yes, what shows lsusb -v? I suppose the first mixer unit is gone in the new firmware. Also Philipp, could you test whether both playback and capture work without any quirk, and with all supported sample rates? At best, test directly like aplay -v -Dplughw:1 some-44100hz-samples.wav supposing the card#1 is the USB device (see /proc/asound/cards). thanks, Takashi > > Thanks for your support and all your dedicated work for the ALSA project > everyone, have a nice week! > > Best regards > Philipp Ludwig > > On 07/29/2018 12:55 PM, Philipp Ludwig wrote: > > On 07/28/2018 10:09 PM, Clemens Ladisch via Alsa-user wrote: > >> a...@philippludwig.net wrote: > >>> usb 3-4: New USB device found, idVendor=19b5, idProduct=0021, > >>> bcdDevice=25.20 > >>> usb 3-4: Product: PX USB > >>> usb 3-4: Manufacturer: Bowers & Wilkins > >>> snd-usb-audio: probe of 3-4:1.0 failed with error -22 > >>> usb 3-4: 2:1: cannot get min/max values for control 2 (id 2) > >>> snd-usb-audio: probe of 3-4:1.1 failed with error -22 > >>> > >>> Any advice on how I could debug this further? > >> > >> Please show the output of "lsusb -v" for this device. > > > > Here it is: > > > > Bus 003 Device 008: ID 19b5:0021 B & W Group > > Device Descriptor: > > bLength 18 > > bDescriptorType 1 > > bcdUSB 2.00 > > bDeviceClass 0 (Defined at Interface level) > > bDeviceSubClass 0 > > bDeviceProtocol 0 > > bMaxPacketSize0 64 > > idVendor 0x19b5 B & W Group > > idProduct 0x0021 > > bcdDevice 25.20 > > iManufacturer 1 Bowers & Wilkins > > iProduct 2 PX USB > > iSerial 3 ABCDEF0123456789 > > bNumConfigurations 1 > > Configuration Descriptor: > > bLength 9 > > bDescriptorType 2 > > wTotalLength 153 > > bNumInterfaces 3 > > bConfigurationValue 1 > > iConfiguration 0 > > bmAttributes 0xc0 > > Self Powered > > MaxPower 500mA > > Interface Descriptor: > > bLength 9 > > bDescriptorType 4 > > bInterfaceNumber 0 > > bAlternateSetting 0 > > bNumEndpoints 0 > > bInterfaceClass 1 Audio > > bInterfaceSubClass 1 Control Device > > bInterfaceProtocol 0 > > iInterface 0 > > AudioControl Interface Descriptor: > > bLength 9 > > bDescriptorType 36 > > bDescriptorSubtype 1 (HEADER) > > bcdADC 1.00 > > wTotalLength 43 > > bInCollection 1 > > baInterfaceNr( 0) 1 > > AudioControl Interface Descriptor: > > bLength 12 > > bDescriptorType 36 > > bDescriptorSubtype 2 (INPUT_TERMINAL) > > bTerminalID 1 > > wTerminalType 0x0101 USB Streaming > > bAssocTerminal 0 > > bNrChannels 2 > > wChannelConfig 0x0003 > > Left Front (L) > > Right Front (R) > > iChannelNames 0 > > iTerminal 0 > > AudioControl Interface Descriptor: > > bLength 13 > > bDescriptorType 36 > > bDescriptorSubtype 6 (FEATURE_UNIT) > > bUnitID 2 > > bSourceID 1 > > bControlSize 2 > > bmaControls( 0) 0x01 > > bmaControls( 0) 0x00 > > Mute Control > > bmaControls( 1) 0x02 > > bmaControls( 1) 0x00 > > Volume Control > > bmaControls( 2) 0x02 > > bmaControls( 2) 0x00 > > Volume Control > > iFeature 0 > > AudioControl Interface Descriptor: > > bLength
Re: [Alsa-user] Bower's & Wilkins PX headphone - snd-usb-audio error
In case anyone reads this, I fixed it myself: 1., I upgraded to kernel 4.18.5 (has probably nothing to do with it). 2., I updated the Firmware on the PX headphones. 3. Then I commented out the complete quirk for the PX in "quirks-table.h", recompiled the snd-usb-audio module and loaded it. 4. Connected the PX to the PC, but no sound yet - fiddled around with the settings in pavucontrol, no result. 5. Then I turned the headphones off and one once. 6. Then I switched the headphones profile in pavucontrol to "off", and then to "Analog Stereo output". Now I got sound. This is reproducible, so I would call this fixed - having to switch the profile once is just a minor inconvenience. Thanks for your support and all your dedicated work for the ALSA project everyone, have a nice week!
