It is repeatedly using SNDCTL_DSP_GETIPTR, which is a wrapper around AUDIO_GETIOFFS, which is unimplemented in isaki-audio2, so always returns 0 (indicating that no frames are available to read). So it assumes that it can't read anything. https://nxr.netbsd.org/xref/src/sys/dev/audio/audio.c#3031 I'll have to think about this.
