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: 05-28-2006 03:58 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. ====================================================================== ---------------------------------------------------------------------- rlrevell - 05-28-06 03:22 ---------------------------------------------------------------------- "So that, according to your judgement, means its working. So why can't I make it work in the real world? For skype or ekiga." Because skype, audacity, and ekiga are OSS apps, and OSS apps block everything else from using the soundcard. It might be possible to solve this eventually but it's difficult. It's much easier if those apps simply add ALSA support... "FWIW, when I start arecord, I get this on the terminal screen but no volume control appears:" I'm not sure what you mean by "no volume control appears". Where are you expecting it to appear? ALSA does not have a volume control per PCM instance - unless the app implements its own software volume control, there is only the global volume control in alsamixer. ---------------------------------------------------------------------- Raymond - 05-28-06 03:58 ---------------------------------------------------------------------- arecord -vv -fcd foo.wav Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz) please, try the plug plugin (-Dplug:default) Hardware PCM card 0 'ATI IXP' device 0 subdevice 0 It seem that dmix and dsnoop are disabled and your card only support 48000Hz http://hg-mirror.alsa-project.org/alsa-lib?cmd=file;file=src/conf/cards/ATIIXP.conf;filenode=38d08ce2e926e4db86d686ddbab08f38a60edaf9;style=raw Issue History Date Modified Username Field Change ====================================================================== 05-23-06 03:52 Gene Heskett New Issue 05-23-06 03:52 Gene Heskett Distribution => FC5, uptodate 05-23-06 03:52 Gene Heskett Kernel Version => 2.6.16-1.2111_FC5 05-23-06 15:01 tiwai Note Added: 0009934 05-23-06 16:46 Gene Heskett Note Added: 0009938 05-23-06 17:24 tiwai Note Added: 0009941 05-23-06 18:07 Gene Heskett Note Added: 0009943 05-23-06 19:14 tiwai Note Added: 0009947 05-28-06 03:08 Gene Heskett Note Added: 0009985 05-28-06 03:20 Gene Heskett Note Added: 0009986 05-28-06 03:22 rlrevell Note Added: 0009987 05-28-06 03:58 Raymond Note Added: 0009988 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
