Hello My mainboard is ECS A780GM-A, the sound chip in it is IDT 82HD206XX6, it shows that below 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) Subsystem: Elitegroup Computer Systems Device 2816 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 16 Region 0: Memory at f9ff0000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: snd_hda_intel
In my bios I don't have a switch to make the font port mode into AC97 or HD Audio. In windows you need to install a driver and set the font port into AC97. In Linux, you can use the font port, but it seems that audio channel is wrong, I can't hear the sound in some part of a film and I can hear the stranger accent of sound in the other part of a film(or a music). But all the 7.1 channel in the back ports can output the sound match my mircophone(all are the same). How to fix the problem? Kernel is 3.4.77
