While searching for Songs for a possible Audition Entry for a Contest at SingSnap®, I discovered that I was getting ultrasonic noise on the Recorder IFrames' VU meters; I traced it to all analog inputs, indicating imminent hardware failure of the Creative Laboratories® SB0350 PCI 2.0 audio card (a 2003-vintage design) in my Hot Rod gPC™.  The Asus® XONAR® Essence™ ST™ fails to satisfy the Hardware Mixing requirement I have due to the use of two or more inputs simultaneously at times.
 
The Creative Technology EMU10K1, EMU10K2, CA0100, CA0102, CA0108, CA10200-IAT, and CA10300-IAT; Motorola MC56361; Aureal AU8820 and AU8830; Yamaha YMF744; and Texas Instruments TMS320C67xx-series DSP's are acceptable under the Hardware-Mixer requirement.  I also have a duplex S/P-DIF requirement.  Analog sources include both +3.6VDC condenser microphones and stereo -10dBV line-level inputs, ideally using 3.5mm TRS jacks.  As with the SB0350, the card is to operate in the context of drivers from the Advanced LinUX Sound Architecture Project.
 
What cards with decent RFI shielding are available, that satisfy the requirements listed above?  And which thereof would be more favored, based on existing reviews here at Head-Fi?

Bump!  I had to fall back on the Gigabyte® GA-MA78GM-S2HP's planar Realtek® ALC889A while awaiting Replies which, as of 24 August 2015, have yet to come in.  Should no PCI 2.n audio card be available that satisfies the criteria listed in the Post above, I will have to use an offboard mixing console with an Asus® XONAR® Essence™ ST™ (Asus® AV-100 DSP, mfd. for ASUSTeK Computer Inc. by C-Media International Inc.; based on the CMI-8788), which is supported with the driver snd-virtuoso by the Advanced LinUX Sound Architecture Project.

Update:  SOLVED
 
Asus® XONAR® Essence™ STX™ (Asus® AV-100 DSP, mfd. for ASUSTeK Computer Inc. by C-Media International Inc.; based on the CMI-8788) is now installed in the Hot Rod gPC™.  Creative Laboratories® SB1550 PCIe 3.0 x1 audio card (Creative Technology CA10300-IAT via ASMedia® PCIe-PCI bridge) had software issues with ALSA, as snd-emu10k1 had been optimized for the EMU10K1, EMU10K2, CA0100 and CA0102; now installed in the Asus® CM1630-06, replacing the STX due to known issues with the audio stack in Microsoft® Windows® 10.0.10586 (see also "Xonar Essense stx Random LOUD high pitched Ringing Noise?").
