    ALSA: Enable PCM hw_ptr_jiffies check only in xrun_debug mode · c87d9732
    Takashi Iwai authored
    The PCM hw_ptr jiffies check results sometimes in problems when a
    hardware doesn't give smooth hw_ptr updates.  So far, au88x0 and some
    other drivers appear not working due to this strict check.
    However, this check is a nice debug tool, and the capability should be
    still kept.
    Hence, we disable this check now as default unless the user enables it
    by setting the xrun_debug mode to the specific stream via a proc file.
