Hello,

Hello,

And sorry about the lengthy delay in response.

Using Ubuntu Mini Kernel v.3.15.3-generic (OSS drivers) I cannot pass 7.1 LPCM and cannot bitstream HD Audio formats. XBMC only detects 2 channels. The xbmc.log only reports m_channel=FL,FR. I can also bitstream AC3 / DTS. I have worked closely with fritsch. We believe this is a kernel audio error with my GPU (AMD 5670.) The setup is dual boot and the Windows partition works correctly, as does the older Ubuntu kernel with AMD proprietary drivers. Debug information below.

• Kernel log (dmesg with drm.debug=0xe):http://paste.ubuntu.com/7811317 • Driver Codec: http://paste.ubuntu.com/7811321 • xbmc.log: http://paste.ubuntu.com/7805000

Strange. Can you please report the output of: speaker-test -D "hdmi:CARD=HDMI,DEV=0" -c8

Also, your kernel log is cut short, and does not contain any audio entries. Maybe try without drm.debug?

Using Ubuntu Mini Kernel v.3.13.0-32-generic (AMD proprietary drivers 14.4) I CAN pass 7.1 LPCM and I can then bitstream HD Audio formats. Windows 7 also detects 7.1 LPCM @ 192khz and will bitstream all HD Audio formats. The xbmc.log reports all 8 channels for m_channels on both Ubuntu Mini and Windows 7. Debug information below.
