A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2108> ====================================================================== Reported By: WhereIsTheCloud Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 2108 Category: PCI - hda-intel Reproducibility: always Severity: minor Priority: normal Status: assigned Distribution: Debian Kernel Version: 2.6.15-1-686-smp ====================================================================== Date Submitted: 05-09-2006 00:28 CEST Last Modified: 07-06-2006 20:22 CEST ====================================================================== Summary: snd-hda-intel: Can only play 48000Hz via digital out. 44100 is garbled. 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!

HD-audio codec has no specific register for SPDIF rate bits. The corresponding SPDIF bits should be automatically updated from the actual rate.
