[linux-audio-user] Latency timer issues

Hi all, I'm trying to reset the latency_timer on my on-board nforce2 sound to 32 instead of 0, but it doesn't seem to work. I issue the command "setpci -v -s 00:06.0 latency_timer=20 as root, but lspci still shows the latency as being 0. Any ideas? 00:06.0 Multimedia audio controller: nVidia Corporation nForce2 AC97 Audio Controler (MCP) (rev a1) Subsystem: Asustek Computer, Inc.: Unknown device 8095 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0 (500ns min, 1250ns max) Interrupt: pin A routed to IRQ 10 Region 0: I/O ports at e800 [size=256] Region 1: I/O ports at e000 [size=128] Region 2: Memory at e6083000 (32-bit, non-prefetchable) [size=4K] Capabilities: [44] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- TIA Rick B
