Hi,
I am using a imx31 based board from Garz & fricke. I need to configure the audio driver from the linux 2.6.23 BSP available. I configured the audio driver by selecting the SSI, ALSA & PMIC Audio options in the kernel configuration. The PMIC Audio card is listing /proc/asound/cards and all the necessary devices are created using the udev available on the rootfs.
I used the check_audio.out application available from IMX PDk BSP test programs. We are getting the following error. I am using the
/unit_tests/check_audio.out 0 /unit_tests/audio8k16S.wav
Hi... playing on /dev/sound/adsp (SSI1) Configuration : 16 8000 2 audio driver write error: Input/output error audio driver write error: Input/output error a
The program is not exiting. also tried with SSI2 as below
/unit_tests/check_audio.out 1 /unit_tests/audio8k16S.wav

But the same hardware is working with WINCE without any issue. I feel there might be issues with drivers that i am using or may some configuration mismatch. Request your help in resolving the same. Request you to provide the troubleshooting steps so that issue can be resolved.
The applications used and the capture of the command execution is as attached.
Thanks & Regards Harish Kumar.B
