A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2192> ====================================================================== Reported By: ccasteyde Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2192 Category: PCI - intel8x0 Reproducibility: always Severity: minor Priority: normal Status: new Distribution: Slackware 10.1 Kernel Version: 2.6.17-rc6 ====================================================================== Date Submitted: 06-07-2006 20:42 CEST Last Modified: 06-07-2006 21:24 CEST ====================================================================== Summary: Very annoying acute sound recorded from line-in with M5455 chip Description: I'm using an ULi integrated sound chip, which reports as a M5455 device, and which works very nice with the intel8x0 driver for playback, but recording sound from line-in input gives corrupted sound with a very acute background sound, except when source gives silence. I have another motherboard (very older, and still with intel8x0 compatible chip), and it gives the same result. ====================================================================== ---------------------------------------------------------------------- ccasteyde - 06-07-06 21:16 ---------------------------------------------------------------------- OK, I've just found what was wrong. The chip records at 48kHz and by default, record records at 44,1kHz. If I tells record to record at the right sample rate, everything is ok. However, I would have expected either an error at ioctl on a device that cannot record at 44,1kHz, either to have a working and transparent resampling. This bug may therefore be requalified to resampling code / library, since it simply doesn't work reliably. ---------------------------------------------------------------------- rlrevell - 06-07-06 21:24 ---------------------------------------------------------------------- What was the exact command line you used to test it? It sounds like an application bug.
