Description: Hi all. I am having trouble getting my computer to play 44100Hz with my digital AV reciever. I have an ECS 945P-A (1.1) motherboard (ICH7), with an onboard Realtek ALC880 8-channel audio CODEC, five miniport(?) jacks, and one fiber optical connector. I use the fiber optical connector to connect the motherboard to my reciever. I cannot get clean 44100 Hz PCM sound outputted. 48000 Hz plays fine. Dmix converts everything to 48000. This is acceptable, but 44100->48000Hz upsampling degrades sound quality. If I dual boot to MS windows, I can select between 44100, 48000, and 96000 Hz output, using the realtek drivers. All work fine and my reciever reports getting the correct format, so it is NOT a hardware problem. I'm not sure if this is a driver issue or a libasound issue. Thank you in advance for your help!

Not being able to play 44100 over Digital Out (spdif) makes it impossible to use passthrough to play DTS/AC3 on an external reciever with files that are 44100hz. 48000hz work fine though.
