저는 BSD를 처음 접했고 오래된 Packard Bell 데스크탑을 트렁크에서 꺼내려고 합니다. amd64용 FreeBSD 10.1-RELEASE의 기본 설치는 잘 진행되고 있는 것 같지만 사운드 카드를 작동시키려는 데 어려움을 겪고 있습니다.
하드웨어는 Intel P4 프로세서로 구동되는 Gigabyte 마더보드를 기반으로 하며 Intel HD 오디오 칩셋을 사용하는 통합 오디오 기능을 갖추고 있습니다. Linux에서 선택된 오디오 드라이버는 snd_hda_intelFreeBSD에서 오디오를 구동할 것으로 예상되는 모듈 입니다 snd_hda.
FreeBSD를 설치한 후 소리가 제대로 나지 않는데, 여러 곳에서 제공되는 온라인 지침에 따라 kldload다른 드라이버를 사용해 보았습니다. amd64 GENERIC 커널에는 sound사전 설치된 많은 사운드 드라이버가 있어서 사용된 노력이 kldload잘못되었다는 것을 알았습니다 . 그러나 파일에는 드라이버가 설치되어 있다는 기록이 없으며 /dev/sndstat, 입력하여 소음을 발생시키려고 하면 cat /random > /dev/dsp작업이 허용되지 않는다는 오류 메시지가 반환됩니다.
내가 알고 싶은 것은 노후된 사운드 카드가 제대로 작동하도록 하기 위해 에너지를 낭비하고 있는지, 아니면 몇 가지 요령을 놓치고 있는지입니다.

답변1
드라이버가 로드 중이라고 가정하면 snd_hda(즉,) 작동 소리가 없다는 것은 드라이버 충돌이나 기본값이 잘못 구성되었음을 나타냅니다. 이 문제를 해결하기 위해 /boot/loader.conf자세한 메시지를 켜기 위해 다음 줄을 추가했습니다 dmesg.
boot_verbose="YES"
이렇게 하면 dmesg다양한 추가 정보가 포함된 출력이 더욱 유용해집니다(참조:이 링크꼭 읽어봐야 할 내용인 것 같습니다.)
여기에서 유용한 것을 추출하면 dmesg다음과 같은 결과가 나옵니다.

오디오 장치의 모든 핀에는 기본값이 할당되어 비활성화되어 장치가 구성되지 않습니다.
기본값을 합리적인 것으로 변경하려면 설정을 으로 변경하여 시작 구성을 수정해야 합니다 /boot/device.hints. 여기에는 많은 유연성이 있는 것 같지만 다음을 시도했는데 오디오 출력이 작동하는 데 충분했습니다. 상자 밖으로:

답변2
FreeBSD 문서를 보면 다음을 발행해야 합니다:
# kldload snd_hda
그럼 해
# cat /dev/sndstat
그래도 문제가 해결되지 않으면 모든 드라이버를 로드해 보십시오.
# kldload snd_driver
# cat /dev/sndstat
소리를 테스트하려면 다음을 수행하십시오.
# cat /random >/dev/dsp
