alsa-project/alsa-plugins issue #19 was opened from elabbing:
Hello, I set 2 host to use aaf plugin for TSN test. I followed TSN-doc guidelines and `aaf.txt` doc. Simply, after hosts is ready and syncing though `ptp4l, phc3sys, qdisc,` then I try to run a basic test, no switch between, back to back linked hosts, obtaining the following error.
``` #Talker sudo speaker-test -p 12500 -F S16_BE -c 2 -r 48000 -D aaf0
#Listener sudo arecord -F 25000 -t raw -f S16_BE -c 2 -r 48000 -D aaf0 | \
aplay -F 25000 -t raw -f S16_BE -c 2 -r 48000 -D default
Playing raw data 'stdin' : Signed 16 bit Big Endian, Rate 48000 Hz, Stereo Recording raw data 'stdin' : Signed 16 bit Big Endian, Rate 48000 Hz, Stereo underrun!!! (at least 24,460 ms long) arecord: xrun:1711: read/write error, state = RUNNING ```
This error happens after a random period, tipically less than 60sec. I followed TSN doc settings, but I noticed that value in aaf plugin configuration and cbs qdisc are suggested differrently between aaf.txt doc and TSN doc.
Any prompt to get out of this? Many thanks
