[Alsa-devel] emu10k1x patch
A few minor fixes to the emu10k1x driver. Also, it would be nice to update the soundcards page to list it as supported (mention that only PCM playback is currently supported). I will try to test a few more things before 1.0.5 gets final, I hope.

[Alsa-devel] Advanced 5.1 + DMIX configuration problems...
I've posted the following message on the alsa-user list a few times and
gotten no response. Especially since it's a fairly complicated setup
and probably a rare one that could reveal certain bugs that wouldn't be
found otherwise, I thought I'd give the development list a shot so the
people who know the nitty-gritty under the hood stuff can comment
-
I first started experimenting with the stereo -> 5.1 configuration and
got it to work great!
Then in the interests of everyone sharing the card, I fiddled around
with dmixing the new 5.1 device and succeeded - now stereo apps are
upmixed to 5.1, share with each other, AND share with real 5.1 apps.
Then I tried to throw OSS into the mix using AOSS. Here's where my
problem is...
A stereo OSS app DOES work in the configuration - for a very short
amount of time. After a variable amount of time (1 to 5 minutes,
roughly) the OSS app will be cruising along and then the next time it
tries to play a sound, it will freeze. Not because the sound card is
blocked, because it happens when nothing else is accessing the card.
But, in the process of freezing, it does block the sound card as nothing
else (ALSA or OSS) can use it until I kill the OSS app.
After it happens once, it seems to happen very quickly every subsequent
time until I reboot. By very quickly, I mean the OSS app may get one or
two sounds off before it freezes 10 seconds into execution.
Here is the asound.conf I am using -
pcm.!default{
type plug
slave.pcm "dsp0"
}
pcm.dsp0{
type plug
slave {
pcm "mixed51"
channels 6
rate 48000
}
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.2
ttable.1.4 0.2
ttable.0.5 0.5
ttable.1.5 0.5
}
pcm.mixed51 {
type dmix
ipc_key 1099234
ipc_key_add_uid TRUE
slave {
pcm "hw:0,1"
rate 48000
channels 6
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}
ctl.mixer0 {
type hw
card 0
}
My soundcard is a CMIPCI (8738) and I am running ALSA 1.04_rc2, as
included in kernel 2.6.5. Notice the hardware device is hw:0,1 as that
is the 5.1 device for this card.
The way I use this setup is as follows -
-OSS apps using AOSS obviously route directly to dsp0. That upmixes the
stereo to 5.1 then uses mixed51 to dmix it.
-Stereo ALSA apps using the default PCM get rerouted to dsp0, or
alternately I tell them specifically to use dsp0
-5.1 ALSA apps I tell to use mixed51 directly as they don't need the
stereo->5.1 hack but DO need to share the card via dmix
Any explanations or solutions are MUCH appreciated - even if the
official developer explanation is "don't do that, it doesn't work" tia

[Alsa-devel] ATI IXP SPDIF
hi, i am trying to get SPDIF output working on ATI IXP/Realtek ALC655 and i am using atiixp.c from cvs (version 1.9) and linux kernel 2.6.5. i tried playing back wav files through aplay and ac3 files with ac3play and i couldn't get any output from either SPDIF over AC97 or SPDIF Direct. analog output is fine. from the cvs logs i gather that SPDIF on ATI IXP should work for some cases at least, has anyone got it to work? if so with what files/hardware/settings etc? i am not very familiar with sound programming or sound card driver operation, but i am willing to help if needed. cheers, alex = Alex Song Software Engineer XVD Corporation 44061 Nobel Drive Fremont, CA 94538, USA Work: (510) 770-5700 x266 Fax: (510) 770-5769 Email: [EMAIL PROTECTED] = --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

Ok, without units it's a problem for everybody :) and what you think of a default units ? or accessors of the internal queue ? if you dont like the hidden queue idea, maybe a macro wich auto-fill the event structure with courrent queuing time could be very usefull !

SND_SEQ_EVENT_NOTE isn't a 'real' event but gets split into two events, SND_SEQ_EVENT_NOTE_ON and _OFF, and the latter must be sent at a later time. Scheduling events to be sent later requires a timer which isn't avilable without a queue. The SND_SEQ_EVENT_NOTE event is the only event that uses the event.data.note.duration field, but you cannot know what the value in this field means without having a timer which specifies how long one timer tick lasts.

Thanks ! that's works ! I dont know where you find this in the documentation, if it's exist :P Remark: Why SND_SEQ_EVENT_NOTE event doesnt accept direct dispatching ? technicaly, there is surely a reason, but conceptualy, I dont see.
