We made a spinoff of a Boundary Nitrogen6q board, we removed the SGTL5000 audio codec chip, we also set BOARD_HAS_SGTL5000 := false in the BoardConfig.mk
However in Android logcat we see a lot of :
W/audio_hw_primary( 2372): card -1, port 0 device 0x2
W/audio_hw_primary( 2372): rate 44100, channel 2 period_size 0xc0
E/audio_hw_primary( 2372): cannot open pcm_out driver 0: cannot open device '/dev/snd/pcmC4294967295D0p': No such file or directory
We have a /dev/snd/pcmC0D0p device, but obviously the 4294967295 is -1 because card in audio_hw_primary is -1.
We can connect audio via bluetooth, it works well, and there is no more error in logcat, however we will not always have a BT speaker connected.
Do I have to change something in audio_policy.conf ? How to remove this error?
Hi,
you need to modified hardware/imx to remove sound card.
Thanks
