I've connected the outputs of the soundard to those of the subwoofer which itself connects the small speakers the following way: Soundcard -------------- Subwoofer --- Small Speakers Out Front <---------+--> In FL <-----> Front Left Speaker \--> In FR <-----> Font Right Speaker Out Rear <----------+--> In SL <-----> Side Left Speaker \--> In SR <-----> Side Right Speaker Out Center/Subwoofer <-> In C <------> Center Speaker \> In Subwoofer Out Back Surround <----> In BL <-----> Back Left Speaker \--> In BR <-----> Back Right Speaker You might have a look at soundcard manual page 8 (http://supportuk.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=574) and speaker manual page 12 (http://supportuk.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=724) My speakers are placed in my room in a configuration as the 7.1 shown on page 12 in the speaker manual. As you note the connection from rear to side is a little bit strange (at least I thought so,...) but this seems to be correct, because when I use the windows mixer supplied by TerraTec itself, there is a surround test included which shows the position of the 8 speakers and let me put the indiviually on and off and this leads always to the correct position. The problem now: I tried the same as under Windows unter Linux with the speaker-test tool. I called it via speaker-test -t wav -c 8 and the following came out: What wav file was played ----- in which speaker position the wav file was played "Front Left" ----------------- Front Left Speaker (correct) "Front Center" --------------- Center Speaker (correct) "Front Right" ---------------- Front Right Speaker (correct) "Side Right" ----------------- Back Right Speaker (probably wrong!) "Rear Right" ----------------- Side Right Speaker (probably wrong!) "Rear Left" ------------------ Side Left Speaker (probably wrong!) "Side Left" ------------------ Back Left Speaker (probably wrong!) "LFE" ------------------------ Subwoofer (correct) No one could think that I should just switch the speaker cables but that can't be a proper solution (not only because this would break settings in the original Windows driver (which I only use for Upgrading my Plextor drive firmware ;) ). I think the configuration of the surround for the Aureon 7.1 Universe has here some mistake, hasn't it? ====================================================================== ---------------------------------------------------------------------- calestyo - 07-20-06 14:47 ---------------------------------------------------------------------- >Does the volume controls change the correct channels ? No they are also switched. >Do you have any multi-media player (e.g. xine, mplayer, ... ) and 5.1 movie to test the surround51 ? speaker-test seem buggy in calculating period size Yes I have,.. but unfortunately I do not have a surround test dvd or so,.. and with an normal movie it would be very difficult to test if everything works correct as background sounds are often very silend and so,.. So what exactly do you want me to test? :D ---------------------------------------------------------------------- Raymond - 07-21-06 04:27 ---------------------------------------------------------------------- >>If the channels are swapped randomly when running speaker-test , this may related to https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2026 >Channels are _not_ swapped randomly,.. they are always exactly swapped like I direct to describe via some ASCII art in the initial bugreport. speaker-test -c 4 -t wav In my case (device hw:0,0 support 1, 2, 4 channels) , the four channels are correct for about 10-20 rounds and the channels are randomly correct afterwards. I expect alsa application use the same buffer size in snd_pcm_writei except the last write. I don't expect speaker-test split the last few buffers into small fragments which some of them are less than the period_size. I have a fix in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2023#9452 which seem to eliminate the swap on my sound card Issue History Date Modified Username Field Change ====================================================================== 06-29-06 01:35 calestyo New Issue 06-29-06 01:35 calestyo Distribution => Debian GNU/Linux 06-29-06 01:35 calestyo Kernel Version => 2.6.17 06-29-06 01:36 calestyo Note Added: 0010634 06-29-06 01:36 calestyo Issue Monitored: calestyo 06-29-06 15:29 Raymond Note Added: 0010647 06-29-06 15:36 calestyo Note Added: 0010648 06-29-06 15:37 calestyo Note Added: 0010649 06-29-06 15:40 Raymond Note Added: 0010650 06-29-06 15:45 calestyo Note Added: 0010651 06-29-06 15:52 Raymond Note Added: 0010652 06-29-06 15:54 Raymond Note Edited: 0010652 06-29-06 15:56 calestyo Note Added: 0010653 06-29-06 15:58 Raymond Note Added: 0010654 06-29-06 16:01 calestyo Note Added: 0010655 06-29-06 16:04 Raymond Note Added: 0010656 06-29-06 16:07 calestyo Note Added: 0010657 06-29-06 16:08 Raymond Note Edited: 0010656 06-29-06 16:12 Raymond Note Added: 0010658 06-29-06 16:19 calestyo Note Added: 0010659 06-29-06 17:50 tiwai Note Added: 0010677 06-29-06 19:05 calestyo Note Added: 0010695 06-30-06 02:02 Raymond Note Added: 0010709 06-30-06 02:14 rlrevell Note Added: 0010711 06-30-06 05:13 Raymond Note Edited: 0010709 07-03-06 19:28 calestyo Note Added: 0010803 07-03-06 19:37 rlrevell Note Added: 0010804 07-17-06 20:49 calestyo Note Added: 0011049 07-18-06 03:23 calestyo Note Added: 0011051 07-18-06 03:23 calestyo Note Deleted: 0011049 07-18-06 05:54 Raymond Note Added: 0011052 07-18-06 05:58 Raymond Note Edited: 0011052 07-18-06 13:37 calestyo Note Added: 0011054 07-18-06 14:24 Raymond Note Added: 0011058 07-18-06 14:25 Raymond Note Edited: 0011058 07-18-06 14:34 calestyo Note Added: 0011059 07-18-06 17:35 Raymond Note Added: 0011067 07-18-06 17:39 Raymond Note Edited: 0011067 07-18-06 18:03 calestyo Note Added: 0011068 07-18-06 18:12 Raymond Note Added: 0011069 07-18-06 18:30 calestyo Note Added: 0011070 07-19-06 03:36 Raymond Note Added: 0011077 07-19-06 05:50 Raymond Note Edited: 0011077 07-19-06 11:50 calestyo Note Added: 0011084 07-19-06 12:03 Raymond Note Added: 0011085 07-19-06 12:06 Raymond Note Edited: 0011085 07-19-06 12:11 calestyo Note Added: 0011086 07-19-06 16:46 Raymond Note Added: 0011087 07-19-06 18:21 calestyo Note Added: 0011091 07-19-06 18:22 calestyo Note Added: 0011092 07-19-06 20:01 tiwai Note Added: 0011093 07-19-06 21:30 calestyo Note Added: 0011102 07-20-06 04:01 Raymond Note Added: 0011106 07-20-06 08:06 Raymond Note Added: 0011113 07-20-06 12:38 calestyo Note Added: 0011117 07-20-06 12:48 calestyo Note Added: 0011118 07-20-06 13:44 Raymond Note Added: 0011119 07-20-06 13:57 calestyo Note Added: 0011120 07-20-06 14:09 Raymond Note Added: 0011121 07-20-06 14:25 calestyo Note Added: 0011122 07-20-06 14:37 Raymond Note Added: 0011124 07-20-06 14:47 calestyo Note Added: 0011125 07-21-06 04:27 Raymond Note Added: 0011142 ====================================================================== ------------------------------------------------------------------------- Take Surveys.
