Alsa card is loaded correctly, but i can hear no sound: omap_rtc omap_rtc: setting system clock to 2014-10-15 15:46:57 UTC (1413388017) ALSA device list: #0: barix-ipam390 UBIFS: background thread "ubifs_bgt0_0" started, PID 1071 UBIFS: recovery needed In the patch, seems "davinci-pcm-audio" is no more a driver. And i should use "davinci_soc_platform_register" to have the pcm helper available. But i don't understand in where i have to call this function. Every help is appreciated. Reagrds angelo
