Dear NXP,
Board: IMX8QM-MEB
OS: Android 9 Automotive
When in BT Call I got the following error continuously,
can not open /dev/snd/pcmC0D0p failed: Device or resource busy.
My question is which card is used for HFP in IMX8QM-MEK Android 9 Automotive ?
XTOR, CS422888, WM8960.
Please provide the HFP stream follow for Android 9 Automotive ?
Thanks & Regards,
Hi, My question is which card is used for HFP in IMX8QM-MEK Android 9 Automotive ?

Hello,
BT HFP should use dummy machine driver imx-xtor.c this will route audio to the real audio codec which for i.MX8QM MEK should be WM8960.
