Hi ALL, in the below link https://github.com/bear24rw/alsa-utils/blob/master/aplay/aplay.c#L1360 My question here is .. aplay -->writes the data from userspace to system dma (in the kernel alsabuffer).and from system dma to hardware dma(if hardware dma present)and to fifo. Now the application writes the data to system dma -->is always fast because the cpu runs in GHz. and from system dma to i2s fifo runs on i2s mclk.which is running on 196.6MHz. My point is.. cpu is always fast and controller is slow ,so when playback we should get overrun. the command should be like this in my point of you. stream == SND_PCM_STREAM_PLAYBACK ? : _("overrun") _("underrun"), Please let me know if I am wrong. Thanks Sujith
