Subject: [PATCH 0/5] ALSA: usb-audio: Delay account cleanup and latency reduction
Date: Tue, 1 Jun 2021 18:24:52 +0200 [thread overview]
Message-ID: <20210601162457.4877-1-tiwai@suse.de> (raw)
Hi,
this is a patch set for USB-audio driver for the code refactoring of
PCM delay account as well as the reduction of the playback latency.
The last change is a bit intrusive (despite of the smallness), and
hopefully it won't break things. My initial tests through various
backends were OK, but if anyone finds a problem, please let me know.
Takashi
