Hello! I´m running linux (rootfs made with buildroot with static device table) booting via U-Boot over NFS. My problem is the sound. The sound chip is found: ALSA device list: #0: S3C24XX_UDA134X (UDA134X) but with madplay I get following error: MPEG Audio Decoder 0.15.2 (beta) - Copyright (C) 2000-2004 Robert Leslie et al. ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card audio: No such file or directory after searching on google i found out that there should be some files in /dev/snd (made by alsa lib, mixer and so on..) There is no such folder. next step I made a device node for snd. /dev/snd exists now but is no diretory. I´m wondering if /dev/**** should be folders or something else. what does kernel do with/in these directories? I compiled in sound support in kernel. in buildroot I configured madplay, alsalib and so on. what could be the problem? please help.
