And there is a problem in CS46xx.conf file, i need to remove the hook on the rear pcm to permit multiple surround40 subdevices to be opened. ====================================================================== ---------------------------------------------------------------------- Raymond - 07-31-06 10:11 ---------------------------------------------------------------------- >> Yes! All the volume controls (front,rear,center,lfe) change the volume of the correct channels. This is true for KMix Do you mean KMix can handle those duplicate controls ( created by TWO AC97 ) ? control.1 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Master Playback Switch' value true } control.2 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 63' iface MIXER name 'Master Playback Volume' value.0 57 value.1 57 } control.14 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'PCM Playback Switch' value false } control.15 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 31' iface MIXER name 'PCM Playback Volume' value.0 20 value.1 20 } control.25 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Master Playback Switch' index 1 value false } control.26 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 63' iface MIXER name 'Master Playback Volume' index 1 value.0 45 value.1 42 } control.27 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Center Playback Switch' index 1 value true } control.28 { comment.access 'read write' comment.type INTEGER comment.count 1 comment.range '0 - 63' iface MIXER name 'Center Playback Volume' index 1 value 59 } control.29 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'LFE Playback Switch' index 1 value true } control.30 { comment.access 'read write' comment.type INTEGER comment.count 1 comment.range '0 - 63' iface MIXER name 'LFE Playback Volume' index 1 value 63 } control.31 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Surround Playback Switch' index 1 value.0 true value.1 true } control.32 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 63' iface MIXER name 'Surround Playback Volume' index 1 value.0 60 value.1 60 } control.42 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'PCM Playback Switch' index 1 value true } control.43 { comment.access 'read write' comment.type INTEGER comment.count 2 comment.range '0 - 31' iface MIXER name 'PCM Playback Volume' index 1 value.0 27 value.1 27 } most likey those controls with 'index 1' is created by the secondary ac97 but it contradict the definition of index control , since there is only one 'Center Playback Volume' and 'LFE Playback Volume' http://www.alsa-project.org/~iwai/writing-an-alsa-driver/x851.htm The index field holds the index number of this control. If there are several different controls with the same name, they can be distinguished by the index number. This is the case when several codecs exist on the card. If the index is zero, you can omit the definition above. cs4294 is 4 channels codec, each codec only control the volume of 4 playback channels in surround51 or surround71 Can any of you post the output of 'alsa-lib/test/timer -list' to https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2257 ? ---------------------------------------------------------------------- bitmage2 - 07-31-06 22:42 ---------------------------------------------------------------------- Raymond, this is about your question "Do you mean KMix can handle those duplicate controls ( created by TWO AC97 ) ?". I presume youre talking about those controls with index 1 (opposed to index 0), right? Honestly, I have no idea when those duplicate controls are uses. The only thing I can say is this: I got all those duplicated devices (like PCM.0, PCM.1 and Master.0, Master.1). And when I change the device state (volume, capture ore playback switch) the change is reflected in alsamixer (and vice versa). For testing I tried to play back more than 32 channels via speaker-test . I did this for checking whether channels 33 and above would go on the second AC97. But ... 1) The channels above 32 just produce nonsense sounds (short, looping sounds) 2) The volume of the nonsense soundss could not be controlled (not by KMix, and also not by alsamixer) Issue History Date Modified Username Field Change ====================================================================== 02-05-06 22:59 darkbrain New Issue 02-06-06 06:32 Raymond Note Added: 0007943 02-06-06 07:10 Raymond Note Edited: 0007943 02-06-06 07:31 Raymond Note Edited: 0007943 02-06-06 07:32 Raymond Note Edited: 0007943 02-06-06 10:46 darkbrain Note Added: 0007945 02-06-06 10:46 darkbrain Note Added: 0007946 02-06-06 10:47 darkbrain Note Deleted: 0007946 02-06-06 18:37 darkbrain Note Added: 0007950 02-11-06 15:01 darkbrain Note Added: 0008018 02-12-06 05:09 Raymond Note Added: 0008025 02-15-06 06:21 Raymond Note Added: 0008076 02-21-06 07:56 Raymond Note Added: 0008152 03-27-06 04:42 Raymond Note Added: 0008987 06-02-06 09:33 Raymond Note Deleted: 0008152 06-02-06 09:33 Raymond Note Deleted: 0008987 06-02-06 09:34 Raymond Note Deleted: 0008076 07-11-06 13:28 Raymond Note Added: 0010970 07-24-06 21:21 bitmage2 Note Added: 0011215 07-24-06 21:25 bitmage2 Note Added: 0011216 07-25-06 02:41 Raymond Note Added: 0011222 07-25-06 05:47 Raymond Note Edited: 0011222 07-25-06 10:18 darkbrain Note Added: 0011224 07-25-06 16:03 Raymond Note Added: 0011228 07-25-06 20:29 bitmage2 Note Added: 0011231 07-26-06 02:21 Raymond Note Added: 0011236 07-26-06 02:26 Raymond Note Edited: 0011236 07-26-06 02:30 Raymond Note Edited: 0011236 07-26-06 08:34 bitmage2 Note Added: 0011244 07-26-06 09:45 Raymond Note Added: 0011246 07-26-06 09:51 Raymond Note Edited: 0011246 07-26-06 09:56 Raymond Note Edited: 0011246 07-26-06 10:04 Raymond Note Edited: 0011246 07-26-06 10:08 Raymond Note Edited: 0011246 07-26-06 10:14 Raymond Note Edited: 0011246 07-26-06 16:26 Raymond Note Added: 0011249 07-26-06 16:28 Raymond Note Edited: 0011249 07-26-06 16:31 Raymond Note Edited: 0011249 07-28-06 05:03 Raymond Note Added: 0011282 07-28-06 10:25 Raymond Note Edited: 0011282 07-29-06 05:13 Raymond Note Added: 0011298 07-29-06 09:06 Raymond Note Deleted: 0011298 07-29-06 12:20 bitmage2 Note Added: 0011299 07-29-06 12:23 bitmage2 Note Added: 0011300 07-29-06 14:02 Raymond Note Added: 0011302 07-29-06 14:12 Raymond Note Added: 0011303 07-29-06 14:50 bitmage2 Note Added: 0011304 07-29-06 14:51 bitmage2 File Added: proc-asound-card0-codec 07-29-06 15:01 bitmage2 Note Added: 0011305 07-29-06 15:03 bitmage2 File Added: test.state 07-29-06 17:23 Raymond Note Added: 0011309 07-29-06 22:44 bitmage2 Note Added: 0011311 07-30-06 03:26 Raymond Note Added: 0011313 07-30-06 03:33 Raymond Note Added: 0011314 07-30-06 03:39 Raymond Note Edited: 0011314 07-30-06 03:41 Raymond Note Edited: 0011314 07-30-06 11:52 darkbrain Note Added: 0011317 07-31-06 05:39 Raymond Note Added: 0011336 07-31-06 05:40 Raymond Note Edited: 0011336 07-31-06 05:43 Raymond Note Edited: 0011336 07-31-06 05:45 Raymond Note Edited: 0011336 07-31-06 05:47 Raymond Note Edited: 0011336 07-31-06 06:36 Raymond Note Edited: 0011336 07-31-06 08:40 Raymond Note Edited: 0011336 07-31-06 09:51 Raymond Note Edited: 0011336 07-31-06 09:56 Raymond Note Edited: 0011336 07-31-06 09:59 Raymond Note Edited: 0011336 07-31-06 10:06 Raymond Note Edited: 0011336 07-31-06 10:11 Raymond Note Edited: 0011336 07-31-06 22:42 bitmage2 Note Added: 0011350 ====================================================================== ------------------------------------------------------------------------- Take Surveys.
