Contents. Introduction Most modern Linux distributions use a hot-pluggable architecture for USB devices.
Pc genius de agostini full version. This is very useful for everyday use, but it becomes difficult for pro-audio use, as ALSA device numbers (hw:X) are not stable across reboots, or even when removed and reinserted. This means that Jack has to be reconfigured after every restart or change. This document describes a method of maintaining ALSA device numbers for USB devices, including MIDI devices. It is not intended for beginning users, as the configuration is relatively arcane. Preparation Ensure that all of your USB audio devices are connected and detected by ALSA.
Do this in a terminal by executing the command: foo@bar:$ cat /proc/asound/cards My configuration is copied below. 0 Intel : HDA-Intel - HDA Intel HDA Intel at 0xefffc000 irq 20 1 BCR2000 : USB-Audio - BCR2000 BEHRINGER BCR2000 at usb-0000:00:1d.3-1, full speed 2 default : USB-Audio - USB Audio CODEC Burr-Brown from TI USB Audio CODEC at usb-0000:00:1d.3-2, full s 3 U0x46d0x8c6 : USB-Audio - USB Device 0x46d:0x8c6 USB Device 0x46d:0x8c6 at usb-0000:00:1d.7-5, high speed 4 U49 : USB-Audio - USB Axiom 49 M-Audio USB Axiom 49 at usb-0000:00:1d.0-2, full speed The first column is the ALSA device (major) number. In this case, on my laptop i have the following:. device 0 (hw:0) is the inbuilt Intel High Definition Audio chipset.
device 1 (hw:1) is a Behringer BCR2000 MIDI controller. device 2 (hw:2) is a Behringer UCA202 soundcard. device 3 (hw:3) is the laptop's inbuilt microphone. device 4 (hw:4) is an M-Audio Axiom 49 MIDI keyboard Take note of your configuration.
Now, in the same terminal, execute the following: foo@bar:$ lsusb My configuration is copied below: Bus 004 Device 001: ID 0000:0000 Bus 005 Device 003: ID 1397:00bc Bus 005 Device 002: ID 08bb:2902 Texas Instruments Japan Bus 005 Device 001: ID 0000:0000 Bus 002 Device 003: ID 0763:0199 Midiman Bus 002 Device 002: ID 0430:0005 Sun Microsystems, Inc. Type 6 Keyboard Bus 002 Device 001: ID 0000:0000 Bus 003 Device 005: ID 0a5c:4503 Broadcom Corp. Bus 003 Device 004: ID 0a5c:4502 Broadcom Corp. Bus 003 Device 003: ID 413c:8126 Dell Computer Corp. Bus 003 Device 002: ID 0a5c:4500 Broadcom Corp.
Bus 003 Device 001: ID 0000:0000 Bus 001 Device 005: ID 046d:08c6 Logitech, Inc. Bus 001 Device 001: ID 0000:0000 Note that active USB devices have two pairs of hexadecimal numbers for an ID, such as 08bb:2902, and generally have a manufacturer's name, such as Texas Instruments Japan. This is where you may have to do some investigation. By removing a USB device and executing foo@bar:$ lsusb you can see which device corresponds to which ID and manufacturer.
In this case, I have detached the UCA202: Bus 004 Device 001: ID 0000:0000 Bus 005 Device 003: ID 1397:00bc Bus 005 Device 002: ID 0000:0000 pid=0x so the internal microphone is vid=0x046d pid=0x08c6 To give the internal microphone the device number hw:1, we enter the line options snd-usb-audio index=1 vid=0x046d pid=0x08c6 Still with me? To configure multiple cards, I had to enter them on the same line, like this: options snd-usb-audio index=1,2,3.' 'n' vid=0x,0x,0x.0x pid=0x,0x,0x.0x where is the vid number of the card corresponding to the card you want to appear first, and is the pid number of that card, and so on. It can get confusing! My configuration looks like: options snd-usb-audio index=1,2,3,4 vid=0x046d,0x1397,0x0763,0x08bb pid=0x08c6,0x00bc,0x0199,0x2902 Information as of 2014, March 20 The restart of the alsa system can be done with the command 'sudo alsa force-reload'.
If that does not help getting the sound working in the USB headset, a full reboot will do it. In one case, on a Logitech USB Headset, on an IBM/Lenovo Thinkpad laptop the above configuration with HDA Intel having the priority as first sound card did not allow for the sound to be output to the headset, so it had to be reverted.
I recently got a new DAC with Mic/Line inputs to also record from analog sources. It's a Tascam UH-7000. My media-pc is mainly running Windows 8.1 but I can dual-boot to Arch. Under Arch, the device is recognized as a USB device, its called TEAC (same company) with lsusb but with aplay -l or aplay -L there are no devices listed.
Does this simply mean the device is not supported on Linux or is there anything I can try to get it to work, at least as a DAC but input support would be grand too of course. I would list more details but I'm unsure what else you'd need. Bus 001 Device 002: ID 8087:8000 Intel Corp.

I own a Tascam UH-7000 USB device but unfortunately it doesn’t work under Linux. Seeing the driver and/or firmware carries your name (Ploytec) I was wondering if you could help me out. Since the device also works on Mac OSX is there a chance this device can be supported on Linux too?
If the source code is available (or at least documented API or something) maybe the Linux community can pick up the development. There are so many nice tools on Linux for recording, editing audio and there are even distributions specifically for audio professionals.
Not having Linux support is really a shame. Thanks in advance! A reply came from one of their managing directors. There’s nothing special about audio on the UH7000, simple isocronous streaming. The intense part would be doing the control panel, if there’s somebody having a couple of months free time for that, I’m sure we can arrange the databooks. Now, I'm not a developer myself and I know most open source developers are volunteers doing their thing in their free time, for free. Still, the reply gives me a glimpse of hope that maybe one day we can have Linux support for this device.
How do things like this go? I have a company possibly willing to work with a developer to support the device in Linux. Where of how would I find a developer who can work with them? Last edited by mouseman (2015-05-05 15:40:53).

Updated on 31. December 2016. Kingrex have resolved the small bug that we have reported for UD384. It’s nice to see a company that listens to their customers. You can get the latest firmware update from their web site. Here is the list of D/A converters that work with AP-Linux.

Few of them we tested in our lab, and others have been reported to work by AP-Linux users. So we cannot guarantee that this information is 100% correct. If you own a D/A converter that works with AP-Linux, send us an and we will put it in this list.
I bought a Mytek 192 now. It perfectly works with my Laptop running Fedora Linux 19 (using MPD 0.17 for playing audio files).
I didn’t install AP-Linux since I had Fedora with MPD already up and running. I just installed the ALSA driver for the mytek following these instructions: The sound quality is great. But I didn’t manage to play DSD files so far. I’ll contact the Mytek support about this. Does AP-Linux include a player that supports DSD?
Is it possible to install that player in Fedora (without installing AP-Linux). As far as I know, this DAC requires drivers for both windows and OSX (no available drivers for Linux). Surfer dude. In my expierence, this DAC on linux, playback capability through USB is limited to 16bits.
Trying to playback at 24 bits sources results in a lot of jitter/noise. I really would like to know based on what you say that it should work without problems? I’ve read that linux should natively support class I and class 2 audio protocols, and this DAC it is supposed to comply with both. Windows does not support class 2 audio protocol, that’s why usually drivers are needed. But on the contrary, OSX natively supports class 2 audio protocol, so it doesn’t need any driver to work with these kind of devices (i don’t understand why drivers for OSX are supplied for this DAC). The same should be true for Linux.
If any of you could make it work with ALSA at 24/192, could you explain how? Hi there Sorry for this very late reply. Up untill now I didn’t try AP linux with the Musical Fidelity V-Dac ii.
Fubar Dac Review
I had other priorities. My system evolved a lot since my posting here about the V-DAC. I upgraded a lot in my system and am now using a Mytek Stereo 192 DSD DAC. I still didn’t have the possibility to build a dedicated linux machine with AP Linux. I’m now using jriver on my macbook pro and still spin a lot of my 3000+ cd collection & LP collection. I’m still planning on building a linux based Music server but that will take some more time & funds I suppose. When I’m going to build it I want to do it decent with decent parts like for instance Paul Pang materials & SSD disks.
For the moment my audio funds go elsewhere. When completed I’ll post my findings about Mytek dac support on AP linux. Grtz & enjoy the Music! I bought emu 0404 PCI card for using it’s optical spdif with my dac. I found this distro and install it on my intel Atom D2700 PC. Everything installed fine but system doesn’t see soundcard. I try enable integral soundcard in BIOS and it works properly but my 0404 PCI don’t.
I think noone got same trouble yet in AP-Linux with same card. I saw discussion in forums about same problem in other Linuxes but I don’t want to install any other software in this system because it may degrade sound quality. It seems to me that the system can’t recognize right the card or a driver. Lspci shows: 02:00.0 Multimedia controller: Creative Labs SB0400 Audigy2 Value.
Please take me advise what have I do to fix this problem. And sorry for my bad english. With best regards Vladimir.
