API? To read a CD you need to, you know, read it =) in very much the same way as PS4 reads DVDs and BDs. The PCM data gained from this can be sent through HDMI or S/PDIF as is. No need to do anything with it with any software.
Actually the Trine 2 devs have already stated that the PS4 port could run at 2160p30fps. It already renders 1080p60 in 3D which requires roughly the same amount of power - the only hurdle is the PS4 not doing 4K output for games right now, which there's no specific technical reason for and could be fixed in a firmware update.

Also, fun fact: Okami HD on the PS3 - not PS4 - has an internal rendering resolution of 3840x2160:

Yes, an API, because software has no direct access to hardware in case you don't know, the OS is managing it.
That's why things like libcdio exist, and in the case of the PS4, it has to be done through the SDK.

WTF really, wonder why.
I just picked up a new TV for the gaming room, normally I'm a sucker for jumping on the bandwagon early however I held back this time round in order to get a good deal rather the latest and greatest.
In saying that I really want to see 4k streaming, and no doubt the next TV (for my living room) will be 4k.
It will be interesting to see is MS and Sony push out hardware revisions (if required) in order to make PSXB41 4k ready.

So software need an API to read a disc in the drive of PS4 now. I wonder how it reads BDs with games without this API at the moment 8)
I'm a system engineer and have been developing software for 15 years now, including an audio CD player when I was back at Uni.
I know how these things work, but just believe what you want.

Ok, let me explain it to you before you'll post another link to a FreeBSD website: since PS4 software can read DVDs and BDs in its drive then the API which you're talking about is already there and there is zero need for anything in software to read CDs. And since CDs are straight PCM encoded there is zero need for software to do anything with the read data. The API which allows that software to send that data to HDMI out is also in place.
The only logical reason why they don't support CD playback after almost 3 years since launch is because the drive itself in current PS4 models can't read CDs physically.
Read that EG interview again: Yoshida said in 2013 (that's less than two years ago, by the way) that both MP3 and CD support would be coming later, and we've got MP3 support added not too long ago. He knows his PR well and would have dodged any reference to audio CD in his answer if the console couldn't read them at all.
You're assuming that Sony went cheap and removed the 780 nm diode, but this makes no sense when 780nm/650nm/405nm diodes combos are today's standard and dirty cheap.
And finally, there's this GAFfer saying that the printed instructions refer to playing audio CDs.
So let it go, dude, it's pretty clear that you have no idea what you're talking about, especially when it comes to how hardware and software operate together in the real life.
I'm done discussing anything else on this subject with you for this reason, but here's some more food for thought so that you can see the stupidity of your last argument: DVD/BD videos are files accessed through a UDF filesystem while audio CDs are not filesystem based but use a specific format known as Red Book. Very different beasts.

Don't have to wait, it was obvious for the PS4 with the teardown at launch. I posted on this two months before the Forbes article created the firestorm by stating that the PS4 and XB1 original versions wouldn't support 4K blu-ray.
Perhaps this should be a new thread? There is so much miss-information and it's not self correcting...no one is using Google Search and doing the necessary research. <sigh>. This negatively reflects on NeoGAF but more so on Articles by professionals .
In the above picture of the original PS4 HDMI chip (same applies to the new PS4 revision):
1) Both are custom HDMI chips.
2) Both have all pins exposed and both motherboard designs make no attempt to hide the video and audio input to the HDMI chip. The video and audio must be encrypted before the HDMI chip! Southbridge handles HDCP 2.2!
The above is lost on just about everyone because they either don't know what a HDMI chip does or didn't notice this. DRM requires every trace or pin that has unencrypted video or audio be hidden inside the board and inaccessible. The HDMI 1.4 chips encrypt inside themselves with key negotiation between transmitter and receiver (Player and TV). In the PS4 designs the video and audio MUST be encrypted in Southbridge as the traces and pins on the custom HDMI chips are accessible.
HDMI 2.0 timings were known but the HDCP scheme was not. Since HDCP takes place in Southbridge it can be firmware updated. The custom HDMI chip supports the faster clock and programmable dividers for HDMI 2 and just passes through HDCP negotiations to Southbridge. All other features remain the same.
Modern Blu-ray drives can support 4K blu-ray There is a 2010 patent from Sony which confirms modern blu-ray drives can support 4k blu-ray. The patent discusses a modification to either the coming 4 layer BDXL in the 2010 blu-ray whitepaper or 3 layer 4K blu-ray disks to make them unreadable on older blu-ray drives by inverting the track information. A software change to later higher spec standard blu-ray drives makes them able to read this inverted track information.
This patent is from 2010 is either about the coming 4 layer BDXL disks or 3 layer 4K and may show that the 3 layer with the 2010 Panasonic-Sony tweak was KNOWN at that time in 2010 to be future 4K blu-ray disk. If it's about coming standard blu-ray drives able to read 4 layers then they can read 3 layer 4K disks. The following cite shows that production equipment to make such a disk was shipping late 2013 which means the standard was known much earlier.
Singulus Develops Technology for 100 GB, 4K Triple-Layer Blu-Ray Discs in 2013
1) A 4K drive has to read 1080P blu-ray disks...
2) The disk standard for 4K was known prior to 2013 when production machines were shipping for those disks
3) Sony was involved in setting the disk standard.
4) The PS4 did not ship till Nov 2013
5) Only the 4K blu-ray format and specs were undecided till this year...I.E. parts that can be firmware updated.
PCs will need a newer dGPU or OEM support for trusted boot and HDMI 2.0 with HDCP 2.2http://forum.blu-ray.com/showthread.php?t=256623 said:
Goto, a well respected Japanese hardware reviewer, speculated the PS4 would have a custom HDMI chip before the 2013 hardware breakdown reveled the Panasonic custom HDMI chip. He never explained why and how it would work and everyone assumed it was a custom HDMI 2.0. He must have known then what the original discover (I cited Ron Jones of the AVS Forum) of the custom nature of the chip means.
You need to understand what a HDMI chip does to fully understand what I'm saying. A HDMI 1.4 chip has a multitude of functions in addition to the video out which don't change from 1.4 to 2.0. For example expanded CEC in HDMI 2.0 is just adding additional commands which are passed through the HDMI chip untouched. The differences are timing/clock/bandwidth and HDCP. The video be it 8 bit or 10 bit is just a stream that has a higher bandwidth (Higher clock) at 60 hz and 10 bit. ALL video generation is done by the player in Southbridge not by the HDMI chip...it just sees a stream of video and audio.
HDMI chips (transmitter and receiver) talk to each other and negotiate an encryption scheme and with supported resolutions the clock timings. HDMI 2.0 has a new HDCP scheme which wasn't known and will be considerably more intense that that in HDMI 1.4 And new resolutions/clock timings which were known.
