Scratchy boot sound on X1000

Hi, from day one, the boot sound on my X1000 has been distorted and scratchy.
It was annoying so I disabled it and forgot about it.

I saw in this thread http://amigaworld.net/modules/newbb/vie ... r=0#683776 that another user has the same issue. Is this a known issue? Is there a solution?

TIA

I do *not* get this problem, however that could easily be caused by either:

1. Me not using the standard(???) "hirasawa.wav" file, but rather an IFF conversion of it (to save a small amount of datatypes conversion overhead that might have been noticable on my Sam440). I guess I can test the standard WAV file if necessary.

2. My sound card is most likely not the same model as used in production X1000s.

Hi Chris, I want to get a sound card for my X1000, which one are you using?

Thanks

As far as my notes indicate, I have a 5-10 year old SoundBlaster128 sound card installed. This probably doesn't help you much...

BTW, what sound card do normal X1000s have?

I also have a SoundBlaster Live 5.1 card and do not have "scratchy" boot sounds.

Model # SB0220

I have not had any sound issues with my X-1000.
I am using a Rosewill RC-701 card, purchased from NewEgg.
This card uses a CMI8738 chip, and has been working fine for me.

I use an audio mixer so that ALL my sound sources can be live
at once, I would definitely have noticed if My X had a scratchy startup sound.

Now my Micro, that thing scratches more than a DeeJay at a Hip-Hop event.
But only until AHI loads up and silences it.

This is my soundcard.
CMI 8738 chip. No brand name to be seen.

Generally sound works ok, except for the scratchy start up sound and loud pops when a new program accesses the sound card for the first time. This second issue was fixed by installing http://os4depot.net/index.php?function= ... hiopen.lha (the scratchy boot sound was an issue before installing this).

I have noticed that when I click on play a test sound in AHI prefs with CMI8738, nothing happens. Is this common?
In all but music unit, the only sound modes visible are those in the pic below.

However if I choose a different sound mode in music unit (see below) I get a sound from play test sound. CMI8738 does not produce a test sound.

I notice you are using Line In and not Mixer for input. Nothing to do with scratchy sound thou.
