Hello, Im running alsaloop test to test the audio on our harware. Im specifically running this command -
alsaloop -C hw:0,0 -P hw:1,0 -S 1 -l 480 -c 6 -v
When I measure the delay through my hardware I get 11mSec - which is fine, and the audio quality is good as well. However after several hours of running this loop test the delay has increased to 90mSec.
Can someone advice what is going wrong here please.
