Dummyś guide for audio with SLACKO puppy linux os - Page 3

i2k92 · 08:25 AM

So I installed Mpdup on an USB flash disk and managed to boot my Intel Atom D410 board with it. Boot up in about 30-40 second, it was able to recognize my Tenor based USB interface and the wizard helps a lot in configuring the mpd.

Being linux dummies, I must admit that it wasn't an easy ride as it took me almost a whole Sunday to figure out how to automatically mount my external USB hard drive (the culprit was NTFS on the external disk). And the BIOS seems confuse the booting process if it has several USB disk connected to it, so I'll order a compact flash to sata interface. Apart of the probelm with NTFS ext disk, it took only about 30 minutes from download to running.

Tested an Android mpd client and it seems to work OK.

I haven't tested the sound quality yet as a friend borrowed my amp. But I'm sure it has potential. It is almost magical to have an Intel machine runs 100% silent without any moving part inside (I uses PicoPSU with external DC block).

As soon as it can produce sound, I'll try to apply a realtime kernel on it. I really hope that it can beat my existing AMD E-350 machine with Win-7 + foobar + jplay.

I very much doubt you will gain any sonic improvement with the rt kernel. Technically there is no reason (at least I have never been able to identify any and nobody presented any either). Also I have never read about a credible listening test confirming any audible difference.

Yes, the developer of mpdpup mentioned that on a minimalistic setup like this the rt kernel will have very insignificant effect (if any at all). But I'll never know unless I test it and it is important as part of my learning curve on Linux.

Well, that is certainly a very good reason.

Extending the topic of suggested multimedia PCs, I wonder how Android TV boxes compare.

Android TV Box - Notebook, Tablet PC & MID

They go for about $100, have pretty good CPUs, WIFI and HDMI. The onboard audio probably sucks but they all have USB ports which suggests they can be used with external DACs. I think they might be fanless as well. I'm not sure how Android handles USB audio but installing Linux should be able to turn those into some serious multimedia streamers.

Especially the native SATA port looks compelling, lots of other devices use only on-board USB/SATA converters

I found "linux Installer" on Google Play Store. It says that it will install Ubuntu variant on droid devices.

Mpdpup works with my onboard sound card and controlled via mpdroid on my smartphone. Nothing to talk about the SQ due to crappy onboard sound, but there's no reason why it won't work with external DAC.

Being a total Linux noob, I'm surprise about how easy to configure this and the author is very responsive in responding even the most stupid question. I really recommend this distro to everyone.

Hi i2k92,
can i install the mdp pup on a a local harddisk that is also the storage device ?
I have a standard atom based motherboard with harddisk , monitor , mouse and keyboard attached .
Keen to try it out also.
Can it output 24/192 signal for the usb xmos converter ?

thank

Selamat siang cik,

I think so, but install it on USB is more practical IMHO. So you can still keep your existing OS installation on the local hdd. Only plug the USB when you want to listen for good music adn you can still use the PC for anything else with your existing disk. If your local hdd is NTFS, there's a trick you can find here :Puppy Linux Discussion Forum :: View topic - mpdPup - Simplified MPD Music Server/Jukebox - v0.9.2

You only need keyboard, mouse & monitor during the initial setup with the wizard. After that you can remove them all, control the playback from Windows client, Android or IOS.

I don't have XMOS but there are some posters on the forum above that use XMOS / WaveIO and most of them uses Alix boards which processor has lower spec than Atom, so Atom should be OK for hi-res.

XMOS is my target once I complete my ongoing DAC project. For now I use Tenor based USB board.

So you guys think this is kinda best bang for buck for digital transport and did anyone stream music from NAS server from these dstro?
