I am attempting to record a DAO Audio CD using cdrdao
(latest version).

My drive is a Pioneer DVR107D

Here is the command I run:
cdrdao write --driver generic-mmc --speed 4 master.toc

Even though I specify a speed of 4X it still says:

Cdrdao version 1.1.9 - (C) Andreas Mueller
<andreas@daneb.de>
SCSI interface library - (C) Joerg Schilling
Paranoia DAE library - (C) Monty

Check http://cdrdao.sourceforge.net/drives.html#dt for
current driver tables.

Using libscg version 'schily-0.8'

/dev/cdrecorder: PIONEER DVD-RW DVR-107D Rev: 1.10
Using driver: Generic SCSI-3/MMC - Version 2.0 (options
0x0000)

Burning entire 74 mins disc.
Starting write at speed 10...
Pausing 10 seconds - hit CTRL-C to abort.

Why is it saying speed 10 if i told it to record at
speed 4?

This is really frustrating, as I am trying to prepare a
gift for someone by making a CD of a live recording.

The recorded WAV file is:
Sample rate: 44.1Khz
Bit: 16 Bit
Channels: 2

When I burn the disc, it seems to burn without buffer
underruns, but when I play it back in my CD Player, I
hear the music, but then an intermittent BUZZ cuts in
and out over the music.

What gives?

I would appreciate any suggestions or help. I'm
desperate to get this project done on time.

Thanks!

    Oh and by the way: the buzz is NOT present in the original
    WAV file.

    Lemme guess, kernel 2.6.8 ?

    That was a bad bug in the DMA buffer code of kernel 2.6.8
    that was fixed in 2.6.8.1.

    The Pioneer DVR107D is known to work so this has to be the
    only possible explanation. I'll close since this is an
    anonymous report.
