我有一台联想 thinkcentre M90，配有板载音频 Realtek Alc662 和环绕 Creative inspire T6100。我只有 2 声道声音。我只有前置扬声器和低音炮的声音。
0 - Front Left
1 - Front Right
2 - Unused
3 - Unused
4 - Unused
5 - Unused
我的 Pulseaudio daemon.conf 有enable-lfe-remixing = yes
default-sample-channels = 6
default-channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe
Pulseaudio 管理器
Default sample type : s16le 6ch 44100Hz
Default Sink: alsa_output.pci-0000_00_1b.0.analog-stereo
alsa_output.pci-0000_00_1b.0.analog-stereo
Sample type: s16le 2ch 44100Hz
Channel map: front-left,front-right
/etc/default/speech-dispatcher有Run=No
我尝试添加
options snd-hda-intel model=3stack-6ch，/etc/modprobe.d/alsa-base.conf但没有结果
我尝试添加
options snd-hda-intel index=0 model=3stack-6ch；/etc/modprobe.d/alsa-base.conf但仍然没有任何效果。
我尝试过编辑/etc/pulse/default.pa
load-module module-alsa-sink device_id=0 channels=5 channel_map=.......
又沒有任何动作。
我尝试过编辑/.asoundrc
pcm.sndcard{
type hw
card 0
device 1
channels 6
}
没有什么
pcm.!default {
type plug
slave.pcm “surround51″
slave.channels 6
route_policy duplicate
}
什么都没有，还有一堆其他配置 - 仍然一样

这是我的 Alsamixer
有什么建议可以解决这个问题吗？
答案1
我们首先要问一些显而易见的问题：
- 您是否尝试过播放任何环绕声源？
- 你的第一步应该从这里开始：https://help.ubuntu.com/community/DigitalAC-3Pulseaudio
我能够使用该方法在类似的音频芯片组上通过 SPDIF 实现环绕声。
