We seem to have a generic IPC4 delay reporting issue on SoundWire devices:
LNL:
aplay -Dhw:0,0 -c2 -r48000 -fS32_LE /dev/zero -B20000 -F10000 -d1800 --fatal-errors -v --test-position
Suspicious buffer position (3044 total): avail = 48, delay = 7493989779945237086, buffer = 960
Status(R/W) (standalone avail=48 delay=7493989779945237086):
state : RUNNING
trigger_time: 568.697921
tstamp : 583.905174
delay : 7493989779945237086
TGL (from @bardliao)
Suspicious buffer position (35432 total): avail = 0, delay = 8646911284551353162, buffer = 960
Status(R/W) (standalone avail=0 delay=8646911284551353162):
state : RUNNING
trigger_time: 120.072871
tstamp : 0.000000
delay : 8646911284551353162
avail : 0
avail_max : 0
@kv2019i @ujfalusi @RanderWang isn't the firmware supposed to provide timestamps that are used for the delay reporting?
This looks like we have a plumbing issue...
