Hi,
Am reading audio using snd_pcm_readi() and using short buffer times
that result in "Broken pipe" errors being returned. Occasionally losing
audio is not a problem, but do I have to completely reinitialise whenever
this occurs?

it depends on the sw params you set up (if any). i think the defau
Hello to all,
who has already done DTMF recognition with ALSA ( OSS )?
I searched for examples in google, but I have found that
only in TODO lists ;-(.
Is this so difficult or why doesn't exist anything about that?

its a relatively trivial FFT problem. use FFTW to analyse the signal,
the
wouldn't it be easier to check for zerocrossings?

I have the working version of the template for the new improved docs.
Can people who have a spare moment have a look through it for obvious
mistakes. Any additions to the text will also be appreciated.
I've looked at it so many times now I need a fresh eye to spot my mistakes.

Are there many cards that have controls switches? If there are not then
I can see a reason to make that component optional to the template.
How should I describe them? I have never

This would assume a perfect sine wave for both tones. The bad thing
about zero crossing is that even the tiniest amount of noise
completely ruins it, and then you're looking at second derivatives,
which are also dependent upon signal quality. Th
I'm looking into ways to automate the modules options component file for
the docs.
At the moment I am considering using perl or mysql. Does anyone know
which is easier to setup to do the following.
Parse the INSTALL file for a module name.
Return the info for that module.
Then either

It looks like support for the CS4630 is rapidly improving! I was
beginning to resign myself to having my Santa Cruz work properly only
under Windows. Thanks folks!
Regarding the discussion about IEC958 ports on the CS4630 and the
CS4297, the datasheets seem to indicate that both have IEC958

I noticed in cs46xx_lib.c that the cs46xx driver defaults to
instructing
the chip that it will be using a 1.03 revision AC97 codec versus a 2.0
revision codec. What are the advantages and disadvantages of this?
