noisy sound with audio cape playback

Hello all,

I am testing my audio cape but sound often comes with noise(sometimes it is clear).

Have no idea about this noise.
Just guessing this might be the driver or codec problem.
so I tried $modprobe snd_soc_tlv320aic3x’ because the audio cape is using the TLV320AIC3106 codec.

but it shows error of ‘Module snd_soc_tlv320aic3x not found.’

List of the audio devices in my system is as follows:

Discard all samples (playback) or generate zero samples (capture)
DA830 EVM,
Default Audio Device
**** List of PLAYBACK Hardware Devices ****
card 0: EVM [DA830 EVM], device 0: AIC3X tlv320aic3x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

Any opinion??


HI Maria,

Were you able to solve the issue of noise in playback with the audio cape? I have the same issue (although I can only get the cape to work by booting off the SD card with uENV.txt edited)
