안녕하세요 언제나 도움을 요청하기 바쁜 하수입니다.
지금 6400으로 진행 중인 프로젝트가 있는데 사운드테스트를
하는데 문제가 발생해서 이렇게 도움을 요청합니다.
alsa-lib와 alsa-util을 크로스 컴파일해서 동작 시키려고 하는데 아래와 같은
메세지가 나오고 동작을 하지 않습니다.
===========================================================
root# aplay /usr/share/sounds/alsa/Front_Center.wav
aplay: main:552: audio open error: Inappropriate ioctl for device
===========================================================
해서 strace를 사용해서 디버깅 해보니 아래와 같은 메시지가 나오면서 몇몇 파일을 찾는데요 alsa를 사용하기 위한 설정파일의 문제인지? 아니면 컴파일 할때 각각 수정이 필요한지 조언을 해주셨으면 합니다.
만약 설정파일을 생성해야 한다면 어떻게 생성해야 하는지 도움을 요청 드립니다.
===========================================================
