The test program does pcm_* operations on loopback devices. You have to insert loopback devices after your system boots up.
sudo modprobe snd-aloop sudo chmod 777 /dev/snd/*
bazel test //:tinyalsa_tests --test_output=all
The default playback device is hw:2,0 and the default capture device is hw:2,1. If your loopback devices are not hw:2,0 and hw:2,1, you can specify the loopback device.
bazel test //:tinyalsa_tests --test_output=all \ --copt=-DTEST_LOOPBACK_CARD=[loopback card] \ --copt=-DTEST_LOOPBACK_PLAYBACK_DEVICE=[loopback playback device] \ --copt=-DTEST_LOOPBACK_CAPTURE_DEVICE=[loopback capture device]
