    Investing your time into Qt is the best investment. Stick to C++ and Python. Both work.

    Avoid Perl-QT though. Not that it does not work, but it makes your brain go numb because you end up writing in pidgin-C++ intersperced with Perl. It overrides perl default OO conventions and uses C++ ones. There are parts where you have to outright put C++ snippets into the Perl code to get it work.

    Tk is also good, but obsolete by today's standards. Its one and only remaining use is writing UIs for Perl where you cannot use web ones.

    In fact, it is exceedingly rare for a non-troll company to actually license something for a fee from another company. If you try to do that, at the second meeting the lawyers of the company you are trying to license to open a FAT briefcase with their patent ammo and you are facing a mutually assured destruction. The sole exemption to this are industry standards with RAND tagged on them. However as the ongoing war in mobile has shown that is broken too.

    This by itself should show that the system is broken. In fact that is what you need to show to _BUSINESS_ people when speaking why it is broken. They do not care about free, blah, whatever, what they care is bottom line and that has a very bad forecast in a Cold war. Cold war on the verge of mutually assured destruction is a guaranteed lose-lose situation.

    The 4th common problem I've found is hissy. Low signal to noise ratio by virtue of high white (pink?) noise level.

    And that one too, though in a lot of cases it can be traced to the power supply. That is one of the reasons why the MiniITX systems tend to behave better - most of their cases have the low freq AC portion out of the case in a separate dead rat. In a lot of cases it is actually not the PC fault. There was a long period between mid-90-es and mid-2000es when the manufacturers did not give a damn about the AUX input on most kit. On a lot of cheap kit from those days you get passable CD playback and surprisingly hissy and crappy AUX. This cannot be helped :(

    The 5th common problem I've found is weak outputs. I have a 1st gen mac mini as sort of a MP3 jukebox and it just barely outputs line level on a good day. It's probably running a bit low to my occasional annoyance. So just run everything at a lower level, resulting in problem #4 rearing its ugly head again hisssssssssssss.

    I am typing this on one of those and I am surprised that you get it to produce tolerable audio in the first place (unless you left it with OSX). My experience with that one is that it skips. It is supposedly fixed in the latest ALSA drivers though.

    The 6th common problem I've found is way funky drivers with creeping featureitis: weird pre-distortion to "expand the stereo experience", equalization that doesn't work as well as a real eq although it clips pretty well, strange attempts at internal DSP to simulate echos. Just turn my bytes into AC voltage and leave it alone, please!

    Most of these can be disabled from a decent mixer even if they are implemented in hardware. The bloody Fuji-Siemens Scaleo and other Intel HD systems are an example at hand here as it has all kinds of unwanted effects you have to put to 0 to get decent sound.

    The 7th common problem, admittedly not too often a problem, is ground loops. Hummmmmmmmmmmmmmm. Gimme a transformer isolated input any day. Not so bad with optical digital inputs of course.

    Aaa.. that one. Now that is a very interesting one. If you perform surgery on the stereo connector on a lot of these you can find that the imbecile designing it has used a 4 contact connector they can do "easy" headphone detection and report headphones presense in software (instead of doing this based on current). That can often be helped by using a 4 contact connector similar to the one used by Nokia for their universal cable (audio+video) instead of 3 (left, right, ground) and doing some soldering of your own. It is of course unnecessary if it is implemented correctly (HP NC4000 is a good example).

    Most VIA EPIAs have sound quality on par with discrete audio solutions. It is something you can hook to a proper amp and not be disgusted by what comes out from the other end. Most via based mini-ITXes can proudly play flac encoded audio with proper Hi Fi quality. So are some of the older Crystal Audio chipsets found on really old high end motherboards.

    Compared to that most audio on Intel chipset motherboards I have had to deal with is utter tripe (with the notable exemption of Asus). The most common problems are:

    1. Interference from the network hardware. As the network works it "ticks" over the audio channel. Makes a PC totally unusable for music. This is more common on older kit, though I still see it here and there even today.
    2. IRQ interference problems on new hardware. I thought that shared IRQ problems are something of the distant (circa 1998) past. Recently Fujitsu-Siemens and Intel proved me wrong. The Intel HD on the Scaleo-E needs special IRQ tweaking on Linux in order not to skip: http://foswiki.sigsegv.cx/bin/view/Net/DebianScaleoE
