A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2147> ====================================================================== Reported By: Gene Heskett Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 2147 Category: PCI - atiixp Reproducibility: always Severity: major Priority: normal Status: assigned Distribution: FC5, uptodate Kernel Version: 2.6.16-1.2111_FC5 ====================================================================== Date Submitted: 05-23-2006 03:52 CEST Last Modified: 06-01-2006 10:34 CEST ====================================================================== Summary: lack of full duplex operation for ati-ixp chipset. Description: skype, ekiga, audacity, and generally any program that needs to both transmit and receive, using isolated paths, fails in playback when recording. In skype, I sound great at the far end, but reception may or may not work, with emphasis on the not. What I hear in the phones, or in the speakers, sounds like what you would get if you took a sentence of spoken words, break it up into say 5ms pieces, and play them at maybe 10 of these little snippets per second, so that the resultant sound is broken up to the point of no comprehension, and stretched in time by a considerable amount. In audacity, simultanious playback, or play one track while recording another, likewise fails in that only very short snippets of the played track are output to the phones or speakers. Likewise, ekiga suffers from this same effect, I'm told I sound great on teh other end, but I can't hear more than half a word occasionally. ====================================================================== ---------------------------------------------------------------------- Raymond - 05-31-06 18:05 ---------------------------------------------------------------------- aplay -L This list all PCMs defined audacity seem not an sutiable application for testing full duplex of a sound card. ---------------------------------------------------------------------- Raymond - 06-01-06 10:34 ---------------------------------------------------------------------- "I have tried compiling both the stable audacity-1.2.3 and the beta 1.3.0 versions with the portaudio=v19 flag set. In both cases, the "ALSA ATI IXP" driver appears as a device selection in audacity's "Preferences" dialog, but if I select the ALSA driver for input and output and try to record, audacity locks up the kernel." Does audacity record if you select /dev/dsp in audio dialog of "Prefenece" with portaudio=v19 ?
