@ -104,6 +104,11 @@ card*/pcm*/xrun_debug
When this value is greater than 1, the driver will show the
stack trace additionally. This may help the debugging.
Since 2.6.30, this option also enables the hwptr check using
jiffies. This detects spontaneous invalid pointer callback
values, but can be lead to too much corrections for a (mostly
buggy) hardware that doesn't give smooth pointer updates.
card*/pcm*/sub*/info
The general information of this PCM sub-stream.
