Subject: [PATCH 0/3] ALSA: Fix XRUN handling of USB-audio implicit fb
Date: Mon, 5 Dec 2022 14:21:21 +0100 [thread overview]
Message-ID: <20221205132124.11585-1-tiwai@suse.de> (raw)
Hi,
this is a patch set to cover a corner-case bug that happens with
the USB-audio implicit feedback mode. When XRUN happens in the
implicit fb full-duplex streams, the driver may get EPIPE error at
prepare but re-issuing fails again. The essential fix is the 3rd
patch but the former two are covering other corner cases I spotted
(only theoretical).
