eXtream Software Development has written a custom USB audio driver from scratch because Android did not support USB audio until Android 5. Even Android 5 and upward has very limited support for USB audio devices (see below) and as such this driver remains very useful for every Android version higher than 3.1. Next to that, our driver provides low latency, making it possible for example to play virtual instruments in real-time on many devices that cannot do this using the Android driver. The driver supports mono, stereo and multi-channel streams, 16-, 24- and 32-bit resolutions and any sample rate that the device provides. If your device exposes internal mute, volume and/or gain controls, they can be controlled as well. For our media player, USB Audio Player PRO, the driver allows to play in bit-perfect, something that the Android driver will never do.
Google introduced USB audio support in Android 5, unfortunately our tests have shown that their driver has several limitations (aside not offering low latency). Please see here for more information:
Keep in mind the aforementioned scenarios are a bit different from connecting the device through the plain old Media Transfer Protocol (MTP) or Picture Transfer Protocol (PTP) mode. MTP enables the end-user to browse the internal memory on the device from a PC as if it's an external storage drive. Microsoft ships a generic MTP/PTP driver with every edition of Windows since Windows XP, so you don't need an external driver for that.
Most Android OEMs offer official driver packages for their devices. Besides the ADB and Fastboot interfaces, these drivers also support proprietary flashing protocols designed by the corresponding device maker. For example, if you want to flash a Samsung Galaxy device, you must install the Samsung USB driver package beforehand.
Note that Microsoft has been shipping a generic ADB driver with Windows for a while, so installing the OEM driver just for the sake of USB debugging might not sound worthwhile anymore. Windows can also check and install the missing drivers on the fly through Windows Update. However, Microsoft-recommended drivers are not always the best choice for complex USB interfaces, so do check out the official driver pack whenever possible.
Now that you've downloaded the suitable driver package for your device, it's time for you to install it. Some OEMs offer standard installer executables, which means you can easily install the whole driver suite by double-clicking on the setup file and following the wizard.
On some occasions, the OEM drivers aren't enough. Perhaps you've stumbled upon a no-name generic tablet, or the flash mode interface of your shiny new phone has yet to get an official driver from its maker. In that case, you can forcibly install an existing driver package for a similar USB interface through Device Manager.

One of the most daunting challenges for people switching from a familiar Windows or MacOS system to Linux is installing and configuring a driver. This is understandable, as Windows and MacOS have mechanisms that make this process user-friendly. For example, when you plug in a new piece of hardware, Windows automatically detects it and shows a pop-up window asking if you want to continue with the driver's installation. You can also download a driver from the internet, then just double-click it to run a wizard or import the driver through Device Manager.
This process isn't as easy on a Linux operating system. For one reason, Linux is an open source operating system, so there are hundreds of Linux distribution variations. This means it's impossible to create one how-to guide that works for all Linux distros. Each Linux operating system handles the driver installation process a different way.
Second, most default Linux drivers are open source and integrated into the system, which makes installing any drivers that are not included quite complicated, even though most hardware devices can be automatically detected. Third, license policies vary among the different Linux distributions. For example, Fedora prohibits including drivers that are proprietary, legally encumbered, or that violate US laws. And Ubuntu asks users to avoid using proprietary or closed hardware.
If you are new to Linux and coming from the Windows or MacOS world, you'll be glad to know that Linux offers ways to see whether a driver is available through wizard-like programs. Ubuntu offers the Additional Drivers option. Other Linux distributions provide helper programs, like Package Manager for GNOME, that you can check for available drivers.
What if you can't find a driver through your nice user interface application? Or you only have access through the shell with no graphic interface whatsoever? Maybe you've even decided to expand your skills by using a console. You have two options:
If a driver is recognized by those commands but not by lscpi or dmesg, it means the driver is on the disk but not in the kernel. In this case, load the module with the modprobe command:
In Windows Vista, Microsoft rewrote most of their audio systems. There are a number of audio APIs in the Windows API, notably dsound.dll, mmdevapi.dll, winmm.dll, and xaudio2*.dll. WinMM and DSound can be considered "legacy" APIs. For Windows Vista, Microsoft rewrote the legacy APIs to route their audio through the main audio system called MMDevAPI. Around the same time, the XAudio2 APIs were introduced as a replacement for dsound. More information can be found on MSDN's User-Mode Audio Components page.
Ever missed the 'Ding' system sound and other standard Windows audio cues? Wine can play them if you tell it where to find PCM .wav files. Because every UNIX is different, Wine can't guess where to find them. See bug 21277 and add a section like this to your `drive_c/windows/win.ini`
Make sure that Wine chose the correct driver backend. Wine should select the correct backend for you. If you don't know which backend is correct, this is probably not your problem. To see which backend Wine chose, launch the Wine configuration program winecfg and click the Audio tab. If you are using a Wine prefix from an older version of Wine, you may have an incompatible driver hard-coded into the registry. Please delete the Audio entry inside of the [HKEY_CURRENT_USER\Software\Wine\Drivers] registry key with the regedit program. If none of the above apply and Wine is failing to select the correct backend, then you have encountered a bug in Wine's automatic driver selection and you should report it.
SDL is a cross-platform graphics and sound library commonly used by games. The Windows SDL library contains support for several audio backends, such as "winmm" and "dsound". If the SDL_AUDIODRIVER environment variable is set, then SDL loads the matching backend, or fails if the backend isn't available.
The solution here is to unset your SDL_AUDIODRIVER environment variable before running Wine. This should restore your audio, as SDL will fall back on one of its default Windows drivers. Alternatively, you can create a new registry entry which will override the SDL_AUDIODRIVER environment variable for your Wine prefix:
Wine's directmusic implementation (dmusic, dmime, dmloader, etc) is very incomplete. If your application uses directmusic for its audio, then it will not play audio. This includes most games made with GameMaker. However, installing both "directmusic" and "dsound" using winetricks should give you working audio.
Wine has official support for PulseAudio. The driver should work well, but there are some known issues with unusual audio buffer and latency settings. If you find you are having choppy or no audio with some applications, then check to ensure the PULSE_LATENCY_MSEC variable is unset, and that you're using default buffering values in /etc/pulse/daemon.conf. Certain audio devices, especially USB audio devices, can cause PulseAudio to use different latency and buffering settings, which can cause issues with Wine. This is a known bug in Wine.
JACK, the low-latency sound server, had a driver in the old driver architecture. It has been removed as part of the transition to MMDevAPI. This means that there is no JACK support in Wine at this time. If a developer is sufficiently motivated, they could implement an audio driver to restore support for JACK. The new driver would be expected to pass all tests, especially those in , , and . An external git tree, frequently synced with main Wine, would be the best way to start. If this is a project you think you might undertake, please contact the wine-devel mailing list before you begin.
WineASIO users need not fear! WineASIO's implementation is completely separate from the old drivers. If your application does all of its audio IO through ASIO, then your audio experience should not change.
Note 2: If you get click noises on output, try the module optionposition_fix=1 or 2. position_fix=1 will use the SD_LPIBregister value without FIFO size correction as the currentDMA pointer. position_fix=2 will make the driver to usethe position buffer instead of reading SD_LPIB register.(Usually SD_LPIB register is more accurate than theposition buffer.)
Note: the binding of amplifier is dependent on hardware.If there is no sound even though all channels are unmuted, try tospecify other gpio connection via amp_gpio option.For example, a Panasonic notebook might need amp_gpio=0x0doption. 2b1af7f3a8
