Why not simply change to an outboard DAC like the DACMagic? That works
very well in my experience.


I tried plugging my Acer Aspire One 751H nettop into a dacmagic via the
usb connection using foobar & asio4all. The sound was absolutely vile!
It sounded like a gurgling 78rpm played on a distant AM radio. Am I
doing something wrong I ask myself?

Maybe you were listening to a net radio station of someone playing a 78.
:-) Can't tell as you don't say what source material you were using.

However you may need to check that the data is being sent reliably via USB.

With my ancient laptop I had to tweak some of the ALSA and Pulse settings
to avoid occasional breaks. But not had to do that with my new laptop.
However if you are using Windows I can't comment on any software tweaks.

FWIW It works well here from a Shuttle using Ubuntu. Details on the
audiomisc website.

I don't use the DACmagic via usb with my fairly new Acer 5738Z as that
works nicely via its optical spdif output using Xubuntu.

BTW For both the above I have a 60GB SSD fitted as the HD.

Slainte,

Jim


Thanks for your insight Jim.

I was listening to both flac and wav files ripped from CDs.
OS is Win XP3.
I wondered if Windows was corrupting the sound in anyway so I installed
Mandriva 2010 on a sdhc card, plugged it into the card reader and
restarted the computer on the card.
The problem persisted even under Linux (using Amarok and Rhythmbox)
I'm wondering if it isn't a hardware related problem.
Unfortunately there is no spdif output on the Aspire One 751H to fall
back on.....

Cheers.
