Hi all, I have an custom embedded board with the i.MX6 SoC which has WM9712 AC97 codec connected to it. This codec supports 3 channels and has 3 DACs. Two 16 bit DACs for Left and Right channel and one 12 bit DAC which can be configured to use one of the AC97 slots. I have modified the codec driver and the SSI driver for the i.MX6 so I can use all three channels. I have selected to use AC97 slot 3 and 4 for Front Left and Front Right channel and AC97 Slot 5 for this third channel. If I use speaker-test utility with: # speaker-test -t wav -c 3 I can hear the sound on all three channels as Front Left, Front Right and Rear Left. Now, I'd like to use pulseaudio server. However, I cannot get a sound on the third (Rear Left) channel. If I run speaker-test I get the sound on Front Left and Front right, but not on the third one. If I run speaker-test with -D hw:0,0 parameter so it directly uses ALSA driver, I can hear the sound on all three channels. I tried adding this configuration options to /etc/pulse/daemon.conf: default-sample-format = s16le default-sample-rate = 48000 default-sample-channels = 3 default-channel-map = front-left,front-right,rear-left Also tried loading alsa module with module-alsa-sink device=hw:0,0 channel_map=front-left,front-right,rear-left But, I cannot get the sound on the third channel. Any suggestions how to configure pulseaudio server for this custom set-up? Is this even possible with my custom set-up? Any suggestions/hints would be appreciated.
