I shall test-drive it, and see how well it reflects the problems
I had, and you fixed!

You'll probably need the 'next' page - which I've not written
yet! :-)

That will cover things like using aplay to investigate your card
playout devices and how to write a suitable .asoundrc to control
and direct output. Thought it best to start with alsamixer, etc,
as it means starting with a nice graphic display showing users
what they have.

However, first, I intend writing a magazine article. Needed a
wepage in place first so I could give a URL to point readers
toward for more specific data. Once the article is done I'll have
a while to add another page or two to the above, and then all will
be findable by someone who reads the magazine.

Slainte,

Jim


Having read the whole article now, one question:
Can I use the Mic Input on my laptop, which already has a built-in
Mic, as a Line Input, or is there going to be some horrid
mis-match? I have a tape deck nearby, and I would like to send its
output into the laptop, but it only has the Mic Input.

In principle yes. However most mic inputs have a dc voltage on them to
power the FET on the microphones. Thus your line out should make sure
it has a capacitive output or you could have a fight.



On a similar vein, but in the opposite direction, I would like to send
the PC headphone output signal to my HiFi, since my stupid TV will
only send out of the SCART connector the sound track from whatever TV
channel it's tuned to, even if the HDMI input is selected for display.
But I know that there is going to be a mismatch between the PC's output
and any input on the amplifier, as it is not designed to accept such an
input signal.
Another idea shelved.
