Source: linux-2.6 Severity: wishlist While CONFIG_SND_PCM_XRUN_DEBUG is mostly used for debugging purposes, it can also affect the behavior of snd_pcm_update_hw_ptr0() since commit c87d973. (See XRUN_DEBUG_JIFFIESCHECK in sound/core/pcm_lib.c.)
This has been used before to work around bugs in intel8x0[1] and cmipci[2], which have now been (mostly) fixed. However, my own sound card will still not play correctly without this hack[3]. It would be nice not to have to recompile the kernel just to enable this option. Note that CONFIG_SND_PCM_XRUN_DEBUG itself only creates a procfile; no other effects will be felt until specific values are written to that procfile. It can thus be safely enabled, and will only bloat up the kernel a little bit. (Then, people like me who need this hack can manually write XRUN_DEBUG_JIFFIESCHECK to the procfile.)
