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: 05-29-2006 03:13 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. ====================================================================== ---------------------------------------------------------------------- Gene Heskett - 05-28-06 13:17 ---------------------------------------------------------------------- re 00010000 (Raymond) That may be true for other distros, but FC5 has only the speaker-test subdir at that location, with everything else in /etc/alsa. As for the audacity mono problem, I've already run into that, and as far as the configure option given, this is an rpm, so I have no idea howto enforce that without installing from the src rpm. If this is causing an alsa/audacity then we should be pulling the packager into this discussion. As for applying the -v option to aplay, it does this: [root@diablo ~]# aplay -v foo.wav Playing WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Plug PCM: Direct Stream Mixing PCM Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 16384 period_size : 1024 period_time : 21333 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 16384 stop_threshold : 16384 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Hardware PCM card 0 'ATI IXP' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 16384 period_size : 1024 period_time : 21333 tick_time : 4000 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 1 stop_threshold : 1073741824 silence_threshold: 0 silence_size : 1073741824 boundary : 1073741824 [root@diablo ~]# NDI if the above is correct. I do not see the device default listed above. But it sounds fine. If its supposed to show 'default' then what file do I check to ascertain that its correct, bearing in mind this IS an uptodate as of 6 hours ago fedora core 5 install, and the files are not in what you seem to think is the std location. -- Cheers, Gene ---------------------------------------------------------------------- Raymond - 05-29-06 03:13 ---------------------------------------------------------------------- audacity 1.2.x - portaudio (Portable Real-Time Audio Library) use "plughw" or "hw" for playback and capture, if you are using a sound card which does not support hardware mixing, you have to stop the other application first in order to use audacity. If you want to run audacity and other applications concurrently , you will need a sound card which support hardware mixing 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 05-28-06 04:04 Raymond Note Edited: 0009988 05-28-06 04:05 Raymond Note Edited: 0009988 05-28-06 04:24 rlrevell Note Added: 0009989 05-28-06 04:51 Gene Heskett Note Added: 0009990 05-28-06 05:10 rlrevell Note Added: 0009991 05-28-06 05:27 Gene Heskett Note Added: 0009992 05-28-06 05:34 rlrevell Note Added: 0009993 05-28-06 05:37 Gene Heskett Note Added: 0009994 05-28-06 06:13 rlrevell Note Added: 0009995 05-28-06 06:29 Gene Heskett Note Added: 0009998 05-28-06 06:35 rlrevell Note Added: 0009999 05-28-06 08:22 Raymond Note Added: 0010000 05-28-06 08:32 Raymond Note Added: 0010001 05-28-06 13:17 Gene Heskett Note Added: 0010002 05-29-06 03:13 Raymond Note Added: 0010005 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
