And a .wav is never mu_law. It is rarely ( but could be) rate of 22050 or one channel. But try aplay testing.wav and see if that behaves better. (It probably will not, but it is worth a try). > Warning: format is changed to S16_LE > Playing WAVE 'testing.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo As you see, it overrides your specification with the one from the header. > imx_pcm_prepare > ret = 0 > period pos ALSA 4 DMA 0 > period size ALSA 1000 DMA 10000 Offset 0 dmasize 4000 > DMA addr 87e20000 > dma enable ret = 0 > period pos ALSA 4 DMA 1 > period size ALSA 1000 DMA 10000 Offset 4000 dmasize 4000 > DMA addr 87e24000 > dma enable ret = 0 > pointer offset 0 > aplay: pcm_write:1262: write error: Input/output error > > Please help me resolve the issue. > > Thanks & regards, > Nikhil > > > Larsen & Toubro Limited > > www.larsentoubro.com > > This Email may contain confidential or privileged information for the intended recipient (s) If you are not the intended recipient, please do not use or disseminate the information, notify the sender and delete it from your system. > -- William G.
