Subject: monotonic raw setup seems buggy
Date: Sat, 21 Mar 2020 15:53:03 +0000 [thread overview]
Message-ID: <20200321155303.GB357@freedom> (raw)
Hi,
I am writting an alsa application and while working on pcm status timings, I
noticed that setting monotonic_raw timings in sw_params while the hardware
device plugin is already running with monotonic timings did not produce an error.
Follow the pcm dump which shows monotonic_raw being set on all plugin instances
but the already running hw plugin instance.
Is this a bug, or am I doing something the wrong way?
