[LAU] Teufel PC Bamster not getting connected on USB?

by David Kastrup

Hi, I just got some older Bamster soundbar model (probably not a keeper) that takes USB either for power (in which case it uses AUX in analog) or also as USB soundcard. In the latter case, however, it just switches itself off after a few seconds. dmesg is [ 1201.960192] usb 5-2: new full-speed USB device number 5 using uhci_hcd [ 1202.098273] usb 5-2: config 1 has an invalid interface number: 3 but max is 2 [ 1202.098278] usb 5-2: config 1 has no interface number 2 [ 1202.107265] usb 5-2: New USB device found, idVendor=10d6, idProduct=1100 [ 1202.107271] usb 5-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1202.107276] usb 5-2: Product: USB Audio [ 1202.107280] usb 5-2: Manufacturer: ACTIONS [ 1203.326284] usb 5-2: 1:1: cannot get freq at ep 0x2 [ 1203.338528] usb 5-2: 3:0: cannot get min/max values for control 2 (id 3) [ 1203.344305] usbhid 5-2:1.3: can't add hid device: -71 [ 1203.344328] usbhid: probe of 5-2:1.3 failed with error -71 [ 1203.456336] usb 5-2: USB disconnect, device number 5 and if I am fast enough (before it switches itself off again), lsusb -v delivers Bus 005 Device 007: ID 10d6:1100 Actions Semiconductor Co., Ltd MPMan MP-Ki 128 MP3 Player/Recorder Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x10d6 Actions Semiconductor Co., Ltd idProduct 0x1100 MPMan MP-Ki 128 MP3 Player/Recorder bcdDevice 1.00 iManufacturer 1 (error) iProduct 2 (error) iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 135 bNumInterfaces 3 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xc0 Self Powered MaxPower 0mA 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 40 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 9 bDescriptorType 36 bDescriptorSubtype 3 (OUTPUT_TERMINAL) bTerminalID 2 wTerminalType 0x0301 Speaker bAssocTerminal 0 bSourceID 3 iTerminal 0 AudioControl Interface Descriptor: bLength 10 bDescriptorType 36 bDescriptorSubtype 6 (FEATURE_UNIT) bUnitID 3 bSourceID 1 bControlSize 1 bmaControls( 0) 0x03 Mute Control Volume Control bmaControls( 1) 0x00 bmaControls( 2) 0x00 iFeature 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 0 bInterfaceClass 1 Audio bInterfaceSubClass 2 Streaming bInterfaceProtocol 0 iInterface 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 1 bNumEndpoints 1 bInterfaceClass 1 Audio bInterfaceSubClass 2 Streaming bInterfaceProtocol 0 iInterface 0 AudioStreaming Interface Descriptor: bLength 7 bDescriptorType 36 bDescriptorSubtype 1 (AS_GENERAL) bTerminalLink 1 bDelay 0 frames wFormatTag 1 PCM AudioStreaming Interface Descriptor: bLength 11 bDescriptorType 36 bDescriptorSubtype 2 (FORMAT_TYPE) bFormatType 1 (FORMAT_TYPE_I) bNrChannels 2 bSubframeSize 2 bBitResolution 16 bSamFreqType 1 Discrete tSamFreq[ 0] 44100 Endpoint Descriptor: bLength 9 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 9 Transfer Type Isochronous Synch Type Adaptive Usage Type Data wMaxPacketSize 0x00c0 1x 192 bytes bInterval 1 bRefresh 0 bSynchAddress 0 AudioControl Endpoint Descriptor: bLength 7 bDescriptorType 37 bDescriptorSubtype 1 (EP_GENERAL) bmAttributes 0x01 Sampling Frequency bLockDelayUnits 2 Decoded PCM samples wLockDelay 512 Decoded PCM samples Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 3 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 2.01 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 33 Warning: incomplete report descriptor Report Descriptor: (length is 1) Item(Main ): (null), data=none Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x83 EP 3 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 1 Device Status: 0x78a0 (Bus Powered) Any idea where I can go from here?

[LAU] Soundcraft MTK22 + jack: first 16 channels silent

by Atte

I have an old problem (also posted in august) that I'l like some ideas how to solve. I have two computers, a laptop and a desktop box running identical setups: Debian stretch with 4.12.0-14.3-liquorix-686-pae kernel and jack version 1.9.10. On the laptop my mtk22 works perfectly, on the box the first 16 channels are silent. The laptop has two usb ports, one is blue (usb3 I guess) and one not blue (usb2 I guess), the mtk22 works with all 24 channels on both ports. The box has several usb ports, some build-in (usb2) and an usb3 PCI card I added. On all usb ports the first 16 channels of the mtk22 are silent. I'm led to believe that the problem is a software/configuration problem on the box, due to: 1) the box worked perfectly with the mtk22 when I ran debian 8 (jessie) 2) the box doesn't work even with the build in usb ports I'm suspecting "something" might be grabbing the first 16 channels of the mtk22 somehow, tried disabling pulseaudio (sudo chmod -x usr/bin/pulseaudio and rebooting), still doesn't work. Obviously I tried with several usb cables, the results are the same: the laptop works, the box doesn't. Any ideas how to approach this, pointers, things to check/try out would be greatly appreciated! I'm pretty lost... Thanks in advance! -- Atte http://atte.dk http://a773.dk

[LAU] Focusrite Novation

by Kirk Reiser

Hello folks: A friend lent me an analog to digital interface that shows up as Focusrite-Novation in lsusb. I am not finding it when I do arecord -l and wondered if anyone had experience with this device and might be able to advise me how to record the output of the device. It has two inputs that can be either quarter inch or XLR. I use nama as my DAW and have jackd installed but am not very familiar with recording from usb devices.

[LAU] [ANN] Vee One Suite 0.9.0 - The End of Winter'18 release

by Rui Nuno Capela

Ahoy there! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are once again released just before the season ends. As before, all available in dual standard forms:<ul> - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The changes for this end-of-season goes as follows: - Introducing Scala micro-tuning classes, borrowed, stirred and refactored from original Nick Dowell's amsynth code, all under the GPL umbrella, of course. - An internal note-key/frequency indirection table is now in place, as a baseline for any micro-tuning implementations. - Whether to use native file browser/requester dialogs is now an effective option when launching under NSM session management (was once disabled initially). - Initializing and/or requesting a New blank preset doesn't open a sample file picker dialog anymore as it was more than nagging while under on NSM sessions. (applies to samplv1 [2] only). - Trying to get CC14 MSB+LSB (course+fine) running status on, no matter whether each pairing event are under 200ms apart. - A little hardening on the configure (autoconf) macro side. In order of (historical) appearance: **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.0 (end-of-winter'18) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Re: [LAU] [Fwd: Re: netJack2: Master doesn't show up as readable/writable client on slave side]

by Jonas neuer

Hey Chris, thanks again for the explanation! Yep, I think I had a pretty big misunderstanding on how Jack worked... Right now the Pis HDMI is connected to a small screen with integrated speakers, later on this will be replaced by my stereo receiver. I've selected the proper device and confirmed its working locally on the Pi. I assumed on Windows when I select the proper device Jack would just take its stream as an input, but thats obviously wrong (I feel pretty stupid now for assuming that :D, but then again I was jsut focussed to much on the goal of getting all audio output from the Laptop to the Pi, basically making the Pi the Laptops default audio device) The thing is, on Windows I can't figure out how to tell any application to route its audio through Jack. For example in Audacity on the Pi I can select JACK instead of ALSA and all the Jack connections show up. On Windows I can only select MME, Windows Direct Sound and WASAPI (also tried installing ASIO, but that doesn't show up either.) And for Virtual Audio Cable (the thing I would need to get the audio from to make the Pi essentially my default audio device, since for most simple applications (browser, games etc) you can't even select the device, they just use the standart device (to which I can set the Virtual cable)) I don't even see a setting where I could put Jack.

[LAU] netJack2: Master doesn't show up as readable/writable client on slave side

by Jonas neuer

Hey Everybody, I'm not really sure if this is the right place to ask my question, but I figured I'd give try. If this doen't fit in here please feel free to tell me so. I'm trying to route the audio output from my Windows 10 Laptop to the HDMI-out of my Raspberry Pi running Raspbian Strech. (Later on I want to run some fancy room correction filters on the Pi). For this I want to use netJack (version 1.9.11). On the Pi I start the Jack server via qjackctl and then run *jack_load netmanger* in the commandline. On the Win10 slave I run *jackd* *-R -d net* (with admin rights, just to be on the safe side). Judging from the console output they both find each other and connect just fine. (All the settings are left to their default values) Now when I want to set up the connection via the qjackctl gui on the master (the Pi) I can select the Laptop as readable client and as output socket in the patchbay. However on the slave the pi doesn't show up in the list. The only thing that shows up is one entry "system" as input socket/writable client. When I turn things around (just for testing) and make the laptop the master, then on the laptop I can find the pi as readable as well as as writable client (input and output socket, once each), however on the Pi (now slave) I cant find anything. Does anybody have an idea what could be the issue here? After hours of googleing I only find basic tutorials from which I've gotten the steps I'm doing, but none covers any troubleshooting... Best, Jonas The output from starting the server on the slave: PS C:\Program Files (x86)\Jack> ./jackd -R -d net jackdmp 1.9.11 Copyright 2001-2005 Paul Davis and others.
