Hi Now I'm creating sound driver. But can't reproduce continuously. So, I would like to ask. I use module of SH to play sound. Player is aplay, sound data is wav file. Q1) When I play sound, aplay said underrun!!! (at least 0.000 ms long) underrun!!! (at least 0.000 ms long) underrun!!! (at least 0.000 ms long) underrun!!! (at least 0.000 ms long) I checked source of aplay, but can not understand about snd_pcm_status_get_state. why snd_pcm_status_get_state return SND_PCM_STATE_XRUN ? What should my driver do (or where should I check) ? Q2) The reason that it can not reproduce continuously seems soc-core.c :: soc_pcm_trigger timing. Call timing of soc_pcm_trigger is slow. What should my driver do to make call timing more fast ?
