The Mac Pro introduced in 2019 has eight PCIe slots:
- Four double-wide slots
- Three single-wide slots
- One half-length slot preconfigured with the Apple I/O card
Mac Pro includes one or two Radeon Pro MPX Modules that occupy slots 1-2 and slots 3-4. You can choose your MPX Modules when you order your Mac Pro or order them separately from Apple. Learn how to install PCI cards in your Mac Pro (2019).
Sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an analog format. The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector. A common external connector is the microphone connector. Input through a microphone connector can be used, for example,. USB Sound Card Adapter BENGOO External USB 2.0 Audio Stereo Sound Card Converter with 3.5mm.

Apple AMD Radeon MPX Modules
Apple currently has four different Mac Pro Expansion (MPX) Modules that contain AMD Radeon Pro graphics processing units (GPUs). Radeon Pro MPX Modules can use slots 1-2 and slots 3-4, and you can install one or two of each module:
- Radeon Pro 580X MPX Module: one module only
- Radeon Pro W5700X MPX Module: one or two modules
- Radeon Pro W5500X MPX Module: one or two modules
- Radeon Pro Vega II MPX Module: one or two modules
- Radeon Pro Vega II Duo MPX Module: one or two modules
You can use Radeon MPX Modules along with other third-party PCIe graphics cards. If you use Boot Camp, using a Radeon MPX Module and a third-party AMD graphics card isn't supported when your Mac is using Windows. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).
Mac Pro Sound Card
Apple I/O card

Mac Pro comes with the Apple I/O card, which has two Thunderbolt 3 ports, two USB-A ports, and a 3.5mm headphone jack. The Apple I/O card comes preinstalled in slot 8 and can't be installed in another slot.
Third-party PCIe cards
You can install many different PCIe cards in your Mac Pro, such as fibre channel cards, fibre networking cards, and pro video and audio interface cards. The PCIe bus on your Mac Pro provides up to 300W auxillary power. If your PCIe card requires additional power, such as a GPU, use the Belkin Aux Power Cable.
Mac Pro supports the same GPUs that are supported by external graphics processors (eGPUs). If you use Boot Camp and want to install a NVIDIA card to use in Windows on your Mac, don't install the card in slot 2. Learn about using AMD graphics cards with Microsoft Windows on Mac Pro (2019).
Some older PCI cards might use 32-bit Option ROMs that aren't compatible with your Mac Pro. If you install a PCI card that uses 32-bit option ROMs, your Mac Pro might not start up correctly.

If you want to add additional storage, you can install a third-party RAID card, such as a SAS RAID card, or you can install the Promise Pegasus R4i 32TB RAID MPX Module in one of the two MPX bays. If you use Boot Camp on your Mac, Windows doesn't support Apple software RAID volumes.

okay-there is no 'sound card' as such (as far as I know) . There may be onboard sound, but nothing user-replaceable. to check if it's working, go into preferences, then sound, then, select line out, connect speakers, play something and it should work. If not, mess around with Audio MIDI setup, and ensure that you have 44khz, 16 bit stereo output.
then do a test on your speakers, then save, then quit Audio MIDI setup. that may fix things. According to M-Audio's website (I think that's who makes the delta 1010), you'd need a PC or G4/G5 with a free PCI/PCI-X slot. Mac Pro will not work, and neither will a MacBook Pro. you'll be needing something firewire based, I'd suspect. plus maybe GarageBand or something along those lines. Sadly, the crystal ball has gone dark and that's all I have for now. But-Mac Pro big, Mac Pro tower, Mac Pro hard to carry. Macbook Pro not that big, Macbook Pro not tower, Macbook Pro not hard to carry.
