I can use a utility called 'tone' that is part of my BSP and it opens /dev/dsp and plays a sin wave through a SPORT port on my blackfin. I can then see this data get through the SSM2603 codec and out to a speaker. And, when I read the codec registers while the tone is playing I see that it is in I2S 16 bit mode. When I use 'aplay test.wav' I get no data across the SPORT port and I notice that the codec registers are now set to 32 bit I2S mode. I'm not sure if this even matters but it is the only difference in hardware settings when I use 'aplay' vs 'tone.' What other data can I look for to help me debug why I can't get data through ALSA and onto my SPORT port? And the card is present in /proc/asound/cards. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
