I finally got around to replacing my aging multimedia setup that consisted of an Creative Sound Blaster Live! 5.1 SB0100 sound card combined with a Cambridge SoundWorks (Creative) DeskTop Theater 5.1 DTT2200 speaker system.
Having been a loyal Creative customer that has used their products since the days of the Sound Blaster 16, I had wanted to wait until the Sound Blaster X-Fi had proper drivers for GNU/Linux before making any major upgrades again.
Unfortunately, I finally tired of waiting and I did what any normal consumer in this situation would do. I voted with my pocket book and gave my money to another company.
I ended up purchasing the M-Audio Revolution 5.1 sound card and a Logitech G51 Surround Sound Speaker System.
Everything sounds great and I am now left with the feeling of "why didn't I do this earlier?".
