I am using yocto build setup and trying to play audio using inbuilt audio card cs42888-audio. Doing aplay -l list the capability of audio cards as below:
root@imx6qsabreauto:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: cs42888audio [cs42888-audio], device 0: HiFi cs42888-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: cs42888audio [cs42888-audio], device 1: HiFi-ASRC-FE (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: imxhdmisoc [imx-hdmi-soc], device 0: i.MX HDMI Audio Tx hdmi-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
As it is clear that card 0 have two audio devices 0 and 1. I want to play 48khz stereo audio through hw:0,0 and 16khz mono audio through hw:0,1. But they are not playing in parallel.
The problem is that if i am playing any one of two audio and start playing second audio; first audio stops playing and 2nd audio starts. But I expect mixed audio to be heard.
I tried changing asound.conf file (used dmix and plug alsa plugin) and added virtual device with desired configuration but parallel playback failed. Though, I am able to play two audio through same device in parallel.
