Hi ,
i'm trying to change the fragment size that the alsa
driver is capturing/playing out. It's currently set at
32 msecs(256 bytes).
They are set in the runtime structure...
runtime->period_max ...etc
Could anybody tell me which file these parameters are
set in the alsa-driver directory?
Thanks
s are added to driver sending buffer every 32 msecs.However this does not match for GSM because it needs only 132 bytes every 64/96 msecs.
Can the driver change the amount of data it gets from the soundcard to suit the codec?

Hi All,
i'm using an open source VoIP application with the

My problem is figuring out the patterns I am
getting with the alsa driver when transmitting
packets.
For instance when I use the GSM codec with a packets
size of 80 msecs and 132 bytes,
Hi All,
with the ALSA driver, what do the OSS substream
mean?If you have a 2 main capture channels, how many
substream would you have?
Also the capture stream is supposed to operate at 8000
Hz per second.Is it possible that it is actually say
8192, a value to the power-of-two?

Hi all,
i'm running the alsa-driver-1.0.0. Im using it with
the OpenH323 application. Packets are transmitted or
received in 32 millisecond intervals or multiples of
32 millisecond intervals.
For example using the G711 codec, packets are
transmitted every 32 milliseconds. For the GSM-06.10
codec
Hi All,
still trying to get the hardware and software
runtime paramters of the driver...
In alsa-driver*/alsa-kernel/core there is the pcm.c
file.
There are 2 functions in this file
snd_pcm_substream_proc_hw_params_read
and
snd_pcm_substream_proc_sw_params_read
Both of these print out to so
basically trying to find out the reason packets
are transmitted at alternate intervals of 64 and 96
millisecondsand the runtime period size is the key
help appreciated,
brian.

Am I right in saying this?

Hi all,
I have an intel810 onboard soundcard.I am using the
alsa driver with a VoIP session.
The intel8x0.c file has a minimum period byte size
of 32 bytes with the minimum no. of periods being
1.The min and max rate is set to 48k.
How can I find out what actual(runtime) size period

Thanks Giuliano,
How can I get a dump of the current hardware configuration space?I have the ALSA driver 1.0.0 installed on my Redhat 9 Machine.

Hi all,
im using the ALSA driver 1.0.0 on two linux machines that connect a voice-over-ip session.
I need to know the minimum fragment size that the alsa driver can take from the soundcard and place in the sending/receiving buffer.Does it depend on the speed that the soundcard is operating at?
