Hi all, I was trying to play audio on Linux Kernel v2.6.31-rc5-davinci1. I have enabled ALSA related following configurations: <*> Sequencer support <*> OSS Mixer API <*> OSS PCM (digital audio) API [*] OSS PCM (digital audio) API - Include plugin system [*] Support old ALSA API [*] Verbose procfs contents [*] Verbose printk [*] Generic sound devices [*] ARM sound devices ---> <*> ALSA for SoC audio support <*> SoC Audio for the TI DAVINCI chip <*> SoC Audio support for DaVinci DM6446 or DM355 EVM
In dmesg, I can see one alsa device. I was able to play back using my old oss based application, but when I tried to play using aplay utility, output was not available. I also tried to use amixer but it failed as below: r...@192.168.1.247:~# amixer cset numid=1 127,127 ALSA sound/core/control.c:1227: ALSA sound/core/control.c:1227: unknown ioctl = 0xc2c85513 unknown ioctl = 0xc2c85513 amixer: Control default element write error: Inappropriate ioctl for device Any suggestions ?
