6 The Virtual PCM Test Driver emulates a generic PCM device, and can be used for
8 the PCM middle layer. Additionally, it can be used for simulating hard to reproduce
11 What can this driver do?
14 At this moment the driver can do the following things:
23 Also, this driver can check the playback stream for containing the predefined pattern,
47 First of all, you may want to specify the pattern for data generation. You can do it
54 To set the pattern for the channel 0 you can execute the following command:
63 The pattern itself can be up to 4096 bytes long.
69 can be used for time delay/speedup simulations. The parameter has integer type, and
73 negative - faster. You can try it yourself by starting a recording in any
77 This parameter can be also used for generating a huge amount of sound data in a very
83 This module can be used for injecting errors into the PCM communication process. This
84 action can help you to figure out how the userspace ALSA program behaves under unusual
87 For example, you can make all 'hw_params' PCM callback calls return EBUSY error by
94 Errors can be injected into the following PCM callbacks:
103 This driver can be also used for the playback functionality testing - every time you
113 this functionality, we can trigger the reset ioctl and check the 'ioctl_test' debugfs
