Hi, I'm developing an 8 channel recorder based on alsa0.9.0beta10 and a
Terratec EWS88mt sound card.
I'm now using a 2.4.18 kernel with the Andrew Morton patches applied. I
really want to be able to record/playback at the full 96k 24bits on all
8 channels simultaneously, but I need absolutely no u
Hello !!! All the nice people out
there
I am new on the list and I need some queries
answered here about the ALSA.
I am trying to develop an application that can
record multiple channels i.e. about 8. I have looked into a few API's but have
not found anything promising. I have a ca

Hello,
I have a Terratec Audiosystem EWS64XL soundcard that has the sam9407 and
cs4232 soundchip.
In the past i used the sam9407 drivers from
http://www.anime.net/~goemon/linux-sam9407/
together with the snd-card-cs4232 driver from ALSA version 0.5.x.
This combination worked fine.
The sam9407
Hi,
we've converted our app from OSS to ALSA in 3 days(!). It's working beautifully, we
just need to get time support running again...
Is there any documentation on the timer api that goes beyond what's on the
alsa-project pages? We're trying to sync Video and Audio, and all we need is a way t

i don't believe that the timer API has much to do with this. its mor

For audio/video sync, we do not use any timer on the sound driver.
We use a concept of delay.
This delay value is a measure of time between "Sample being placed in the
audio buffer now" and "Sample being output to speakers".

its often called "UST" (Unadjusted System Time). Its part of the POSIX
CLOCK_MONOTONIC specification. this is su

actually it does. but not woken up from poll, just from snd_pcm_write.
