Hi all!
As promissed, here goes a quick and dirty example showing how to program
the emu10k1 chip (found in the popular Sound Blaster Live! card) with
the ALSA drivers. The example requires ALSA CVS from today and the
alsalib source code in order to compile and run.
The DSP program already harco

Hi all,
these enhancements are in CVS for PCM API:
- added snd_pcm_avail() function - this function returns count of
available frames for write or read operations, the position
is read directly from hardware; the snd_pcm_avail_update() call
is still mandatory before any I/O!!!

I might be a complete idiot, but when I load up the usb-audio drivers
for my extigy out of the cvs tree, I'm not even getting the devices I
need to test the stuff. I'm using devfs, and and hwC0D0 doesnt pop

I the same guy that once claimed that he was going to work on drivers
for the extigy.
Thankyou, I will use snd_pcm_drop(), but as a side note, what actually
does "snd_pcm_reset()" do.
Just resetting delay to 0 does not make much sense to me.
It drops all samples in the ring buffer (thus reseting delay to 0). Note
that everybody are welcome to improve the current do
Hello ALSA developers,
I was wondering if there is a requirement list for
1.0.0 release of ALSA. If not, what would be expected
in a 1.0.0 release? (I've got a few brain/cpu cycles
to spare towards a 1.0.0 release)
I know the topic of sound deamons has really been

Hi,
can anyone test the latest cvs snd-usb-audio driver with the SB
Extigy?
now the names of mixer controls on this device became more
understandable.
the mixer topology of extigy is depicted in
alsa-kernel/usb/usbmixer_maps.c. unlike other usb devices, this is a
really complicated one.

I answer to the original poster first. The Emu10k1 is *locked* at a
48Khz rate. All sources and outputs will be converted to and from this
rate for processing
