oss_audio_device.channels(nchannels) Set the number of output channels to nchannels. A value of 1 indicates monophonic sound, 2 stereophonic. Some devices may have more than 2 channels, and some high-end devices may not support mono. Returns the number of channels the device was set to.

oss_audio_device.bufsize() Returns the size of the hardware buffer, in samples.

exception ossaudiodev.OSSAudioError This exception is raised on certain errors. The argument is a string describing what went wrong. (If ossaudiodev receives an error from a system call such as open(), write(), or ioctl(), it raises OSError. Errors detected directly by ossaudiodev result in OSSAudioError.) (For backwards compatibility, the exception class is also available as ossaudiodev.error.)

ossaudiodev.openmixer([device]) Open a mixer device and return an OSS mixer device object. device is the mixer device filename to use. If it is not specified, this module first looks in the environment variable MIXERDEV for a device to use. If not found, it falls back to /dev/mixer.

ossaudiodev.open(mode) ossaudiodev.open(device, mode) Open an audio device and return an OSS audio device object. This object supports many file-like methods, such as read(), write(), and fileno() (although there are subtle differences between conventional Unix read/write semantics and those of OSS audio devices). It also supports a number of audio-specific methods; see below for the complete list of methods. device is the audio device filename to use. If it is not specified, this module firs

winerror Under Windows, this gives you the native Windows error code. The errno attribute is then an approximate translation, in POSIX terms, of that native error code. Under Windows, if the winerror constructor argument is an integer, the errno attribute is determined from the Windows error code, and the errno argument is ignored. On other platforms, the winerror argument is ignored, and the winerror attribute does not exist.

strerror The corresponding error message, as provided by the operating system. It is formatted by the C functions perror() under POSIX, and FormatMessage() under Windows.

filename2 For exceptions that involve a file system path (such as open() or os.unlink()), filename is the file name passed to the function. For functions that involve two file system paths (such as os.rename()), filename2 corresponds to the second file name passed to the function.

filename filename2 For exceptions that involve a file system path (such as open() or os.unlink()), filename is the file name passed to the function. For functions that involve two file system paths (such as os.rename()), filename2 corresponds to the second file name passed to the function.

errno A numeric error code from the C variable errno.
