Subject: snd_pcm_wait returning EPIPE
Date: Thu, 7 Oct 2004 11:26:34 -0400 [thread overview]
Message-ID: <20041007152634.GK12858@zewt.org> (raw)
I've disabled the underrun state, eg. setting
snd_pcm_sw_params_set_stop_threshold to dsnd_pcm_sw_params_get_boundary,
which results in EPIPE never being returned from snd_pcm_wait (as I wanted),
so I can handle underruns myself. I'm opening hw:0 directly, to avoid
resampling.
However, I'm receiving a report of a system returning EPIPE:
https://sourceforge.net/tracker/index.php?func=detail&aid=1035604&group_id=37892&atid=421366
https://sourceforge.net/tracker/download.php?group_id=37892&atid=421366&file_id=103978&aid=1035604
This is apparently on an x86-64 system.
Is this a known problem? Am I probably doing something wrong that just
happens to usually work? I'm treating EPIPE as an unexpected condition,
since it's not clear why it would happen here; should I have it call
snd_pcm_prepare() and retry anyway?
