The slow down playback is a mismatch sampling rate problem. The I2S clocks for the DAC section all derived from the single 27MHz crystal, so there should be a PLL circuitry there, generating 44.1KHz or 48kHz master clock, then the bit clock and word clock. Very easy to see on the scope, obviously :)

[@WOKFM]

I agree. This is a Sample rate issue. Recording from the radio, just recorded at the wrong sample rate, and thus played back correctly (at a lower sample rate). Everything that had been recorded at 48/44.1 (ie the original HDD recording or the CD natively) is playing back at the wrong sample rate.

[@crunchyfrog555]

I would agree. Listening to it playback it sounds like it's near anough half speed as it's tonally in the same key or thereabouts. I haven't checked of course, but I suspected it was a mismatch or some sort of division problem.

[@WOKFM]

@@getmefix1921 I took the audio from Mark’s video and aligned it to an original recording. With a speed multiplier of exactly 1.5, Mark’s audio aligned perfectly. This suggests that 48Khz audio is playing back at 32KHz. This suggests that it’s not a problem with the 27Mhz itself, but more with a selection on the PLL to derive the appropriate sample clock. Since 32Khz is a valid sample frequency, I would suggest that selection of 32/44.1/48 is controlled by software, driving some tracks in to the divider / PLL device feeding the DAC (and ADC). Could even be a resistor dropped off, or a dry joint, if this is controlled by 2 lines, giving a binary selection of 4 possible sample rates, and the loss of one track is selecting 32 rather than 48. (I appreciate the ripped CD would be 44.1, so this isn’t an exact diagnosis, but the ratio is suspicious). I reckon this is an easy one to trace, looking at the DAC/PLL and not to do with the main processor itself.

[@cls9474]

@@WOKFM Yep. The sampling clock would be my guess too. The clock drives the output shift registers in the main chip. The CD rip is purely digital and has no effect on the playback speed. It's just data.

[@andersvandegevel8355]

The fact that the CD player worked at the correct speed after being in the PC, and until it was used to record to HDD, tells me it is 100% a SW setting. I would trawl through all the menus, and like other commentors have mentioned, check for a dead RTC battery

[@EsotericArctos]

It could also be a hardware ADC or DAC issues as the whole stream looks digital. It's not using analogue audio from the CD drive.

I wonder if it would have kept playing CD’s at the correct speed if not for the rip test (when the drive spun up beyond 1x)

[@FHacivelioglu]

Hi Mark, I think the problem is related to the sampling rate on the digital section. For example, if a track has a real sampling rate of, let's say, 48KHz, but the device plays it at 44.1KHz, then you will hear a similar slow sound and vice versa. You have the schematic and have access to different boards. Please check 24.576 or 12.288MHz (for 48/96/192/384KHz sample rate) or 11.288 (44.1/88.2 etc.) crystals if available. Other than these perhaps some external automatic sampling rate converter (ASRC) IC may be available and does not sync to the main DSP/DAC etc. For example, some DACs or ASRCs may have default 44.1KHz own clk whilst the sync pathway provides 48KHz. On I2S communication you will need 3 wires minimum; BCLK (bit clock/Sample Rate), LRCK, DATA and optional CLK.

[@mosaiques23]

Yeap!! Agreed.

Notable that the recording of the radio sounded fine.. as if the sample rate of the recording matched the sample rate of playback

[@mosaiques23]

[@jaycee1980]

Indeed. The CD playback would be done using DAE.. effectively the CD drive is "ripping" the digital audio and this is being played back by the main board. Almost certainly something wrong with the master audio clock.

[@themadmallard]

[@El-Monopolio]

[@trevor245]

Your initial theory for as to why the cd playback was half speed would likely not ever have been the cause. A cd needs to spin at a fast enough speeds to be able to read the data. If it is half speed it simply wouldn't function. And since this device also reads the track titles and stuff there is likely a form of buffer that first reads the data nad plays it back not from the cd but from the internal storage instead. I think your issue is either a software setting or an issue in the dac circuitry. If there is no software option for playback speed there likely is a mismatch between the bitrate that is being supplied to the DAC and the bitrate the DAC is converting. I do not know how to repair DACs but I would assume that this could be caused by a faulty capacitor or similar component preventing a chip from performing one of its functions.

[@glynnetolar4423]

I concur, I know if I show down a CD player enough it will fault. And it's like not even 10% slower before it will fault. And when I say fault I mean it will quit and spit the disc out.

I can't speak for the Sony but as for the Yamaha, in my opinion is what CD players should have become! It doesn't do network streaming and I think that it doesn't need to, it has a user replaceable internal HDD which contains all the music I want it to. Nor does it have a built-in tuner but should I need to record from the radio, I have the ability to record from anything connected to the system.... I'm old school so I like my hi-fi in a stack of components, I never really was a fan of Yamaha equipment, I have always gone for Sony or Technics, but I came across this Yamaha CD/HDD recorder which I never knew that such a device existed and I started looking into what else Yamaha had to offer! I was surprised to find that Yamaha had literally tried everything! There's a system component that is perfect for everyone!

[@stankogalic3701]

Playback is slow when you play CD and also when you play from HDD. Probably the same thing will happen via USB port so i didn't understand your inspection on optical drive. Capacitors were bad but that did not have anything with slow playback. A bit of wasted time on your part inspecting optical drive. FM tuner playing just fine so there must be a problem on the main board related to sampling rate or something similar somwhere around. I am not expert for that, just some logical thinking. Can't wait part 3 if there will be something. Best wishes!!

Reminds me of a time in the early seventies, when Belgium went from 110V Two Phases mains to 220V Three Phases mains. My dad laid the wiring in our house himself but at some point he had to change stuff and my cassette player played at half speed, or thereabouts. I remember I had a tape on which I recorded 33rpm songs at 45rpm speed and they played almost perfectly when the voltage in the house was switched back from 220 to 110Volts Two Phases.

[@matt-g-2501]

I like your videos. And sometimes it‘s a tricky candidate on your desk and challenge you. Hint: both CD and harddrive use the same IDE bus and both running slow. Before the DAC is a buffer controlling the speed of data delivery from the IDE bus. And even with half speed it still sound like music. If there is a mismatch of sample rate it will never sound like music.

I think it is missing a lower bit somewhere in DAC counter. You can probably check FM and see if it's output is below 12 kHz then it is operating in that same low sample rate, but sounds normal because audio loop routine is bound to sound frames and it just encodes the radio input in same clock

Mark, check the capacitors on the XTALs for goodness! I've had various microprocessor designs that show a 'typical' waveform from a crystal, but it wasn't clean (or sinusoidal enough) for the micro to see it as a stable clock and if the clock isn't stable, then the internal PLL will be all over the place trying to lock onto it. Another thing to check is the display clock frequency (in the comms from the micro to display) when it's running at normal playback and when it's running slow. That will confirm it's a processor clock and program execution speed issue.

I think the "slow" playback is rather a stuttering, like the DAC is going into an underrun then is fed the next chunk of WAV data via DMA again (maybe you can see it looking at the output waveform with a scope). I'm guessing something is overwhelming the CPU with interrupts, that's why it can't keep up feeding the DAC. The radio is probably not going through the DAC, so it's working fine. Either it is a component on the mainboard, like a for example an RTC with a defective battery or goldcap which makes it fire its alarm interrupt all the time, or it is actually the HDD. Constant IDE (error) interrupts can also make the CPU slow down to a crawl. If its not the HDD it can also be the IDE cable - yes they can go bad!

Watch, there probably bis a setting that can be made by the front panel. Get a repair or maintenance manual or at least an owners manual. After all it is a computer with a display and a hard drive so there may be an optional setting to be had on the display via buttons.

[@WombatsNews]

Yes, It will be in the owner's manual under playback and using the remote

I know you are probably a busy guy but I love the videos every time I see u post a video I watch all they through I always want more videos from u and keep up the good work Mark 💯

[@peteshulver9221]

I was surprised you didn’t check for power to the laser assay or checking it was moving to try to scan the disc before actually replacing it or did I miss something 🤔

You've got yourself a vaporwave machine.

[@buddysmith7462]

check the settings there may be a way to slow the speed down and it may be set to slow mode.. just a thought

[@michaeldibb]

The CD is playing slow, but wasn't the MP3 (3:38) from the HDD also playing slow? Which points to something else in the machine? Great video as always! :)

Sample rate settings could be set wrong.

[@DumahBrazorf]

probably it have been ripped from a cd like Mark did. so "good" mp3s into the hd or the cd (does it read mp3s?) would play correct.

[@Mr_Wh1]

@@DumahBrazorf What?

[@Xaelloss]

The device is most likely set to play back at a fixed sample rate that's twice lower than regular CD 44 kHz. It recorded the radio at it so the playback there was fine. I would look in the system settings, perhaps do a factory reset if it has it.

[@RaduTek]

IMO it has to be a software playback speed setting. The device is basically an embedded computer, with a discrete DSP chip, probably because the embedded CPU it has is not fast enough to do audio processing or encoding/decoding. If it was a hardware issue, it wouldn't be working at all or malfunctioning wildly.

Good work👍

[@michaelridley5457]

windows media player has speed adjust settings and suspect the jukebox unit might have a similar feature or maybe try a different cd recorder in the jukebox if jukebox can be reset, is worth a shot. Would like to know the fix for this. Great videos, keep up the good work

[@bernhardingebrigtsen877]

The problem is in the DAC chip. The file content on the HDD is in 44.1 KHz and so are the CD. But the ADC is in 48khz. It’s not switch between those sample rates. Therfore you have perfect recording from FM radio, i think it’s recording in 48Khz and therfore its sounds right. Check the sample rate.

The Rolling Stones play in a nursing home at the age of 95. 🙂 The music from the hard drive was also slow. It's probably the motherboard. Have you tested whether only the HD or the CD drive is connected to the controller cable and not both together? Maybe it's just a cable problem?
