Hi
- I work with tx1+SDK 28.2; the speaker device is tas5751 with i2s4(0-4), it always sound less. I have no idear to debug it!! help help help
- kernel show trace as follow :
[ 18.067337] tegra210-i2s tegra210-i2s.0: Failed at I2S0_RX sw reset
[ 18.082612] tegra210-i2s tegra210-i2s.0: ASoC: PRE_PMU: I2S1 DAP RX event failed: -22 - my dts as follow:
4）additional important info : aplay can not work until few seconds going on
trace as follow:
ALSA lib pcm_hw.c:1700:(_snd_pcm_hw_open) Invalid value for card
aplay: main:722: audio open error: No such device
