I've noticed that when I play mp3s and read text in another window it
tends to make the mp3 sound distort, does anyone know what could be
causing this? because if I disable speakup and let it continu with
incomming text it  doesn't distort the sound. I only get the distortion
with speakup running, any ideas?

Re: curious

[Jason]

that could be any number of things, what's your processor speed, physical 
RAM, and kernel version number?

it's definitely a timing problem.
compile the alsa modules and you won't have a problem.
I've never looked back.
I have here a pentium 200 with 128Mb ram and it seems to fly quite
nicely.

I've noticed this problem while using the kernel sound drivers.
However, it disappears when alsa is used.

ponders.... I've seen a lot about alsa on hear.... is there anyone that
can give me a general idea of what it is how well it works with speakup,
and how well it works with debian and how it works in general?

Re: curious

[Jason]

well as far as "in general" goes, it works wonderfully, it's not as easy to 
install as the kernel based drivers however.

basically as far as I can tell, there is a marginal improvement in sound 
quality over OSS and the Windows sound system when using ALSA.

Alsa or the advanced Linux sound architecture project is an alternative
to the kernel sound drivers.
It works very well with speakup and all Linux distributions.

Re: curious

[Frank Carmickle]

Hi Deedra

What synth are you using?  I'm gonna guess it's a dec express?  Yes you
guys are some what on to this as a kernel audio driver problem.  It
probably will go away with 0.5.11 alsa but it's probably going to reappear
when you move to 0.9 alsa.  That is unless you make the buffer sizes large
enough.  It is generally the case with mp3 players to have a large buffer
size.  You may notice that you will need to pass aplay the flags to open
the audio hardware with a larger buffer size.

What's happening here is that speakup needs to use the processor to send
it's data to the serial port for your synth.  If your reading your
probably sending 50ms worth of stuff sleeping for 500ms and waking up
again to do the process all over.  When you only have a few ms worth of
audio buffered this is gonna run out quickly.  

Most of the time no body really cares if there audio takes 100 ms longer
to start and stop playing so it isn't a problem.  Most of us really enjoy
having a kernel based screen review package so what do you do.  If you
really need lowish latency your going to either have to get a machine with
more then 1 cpu or get a second machine to use as a terminal just to run
speakup on.  But like I said most folks will never need this.  Only those
of us who want to use a low latency audio recording and editing
environment will need this.  

The linux audio development folks have been working hard on pushing the
alsa and kernel folks to make linux a viable low latency operating system
for audio.  There doing a good job with it.  Right now it is required to
patch the kernel with Andrew Morton's lowish latency patches.  There is
also a preemptive patch that gets similar results which uses a totally
different principle to achieve the results.  Uncle Linus doesn't really
like any of the offered solutions thus far.  Let's hope that they get this
stuff hammered out during the 2.5 tree so we can have alsa and low
latency kernels when 2.6 is released.

To whom ever it was that wrote about timings your sort of missing the
point.  You can sit there and stare at the rtc til the cows come home.  
But if they took your cpu away from you for 50ms what are you going to do?

[Kyrath. (AKA Rob)]

Hi, I've finally have obtained everything I need to install slackware 9.1, at least I think so.
However, I'm curious as to why my harddrive is being assigned hdb instead of hda.
In addition, linux, and windows for that matter, are unable to detect my HP cd-rw drive if the Matshita dvd drive is connected.  Does anyone have any idea
of why the Matshita and HP won't get along on the same ide cable?  I suppose that I could connect one the cd drives with the harddrive, but that would
require purchasing a new cable.  The one that connects the harddrive is too short to reach the cd drives.

Re: curious

[Gregory Nowak]

Sounds to me like you need to go back and recheck your jumper settings
in respect to both your hd question and to the cd drives.

Re: curious

check the jumpers.
the hard drive which I assume is on the first ide controler (ide0) 
should be set to master.  The 2 other drives which I assume are on ide1 
should be set to slave and master, with one being master and the other 
being slave.

If you're going to use 2 of those drives at the same time put them on
seperate ide cables.  A hard drive and cd berner  will perform better if on
seperate cables.

true. this is especially noticeable when copying a cd when both the 
cdrom and the burner are on the same ide controler.

As far as the CD & DVD drives, you might try switching which one is jumpered
as master, and visa versa to the slave.
