  • RPi5 with three TV tuners

    Please keep in mind, that the RPi5 itself needs more power, than previous generations. If the system is very CPU agile and not in the idle state, then attaching of USB devices could be the worst case for the power supply and/or the PMIC.

    If your USB HUB is really a powered one, you should try to only attach 1 tuner to the RPI5 directly and 2 tuners at the powered HUB.

    Only to be sure, you attached the RPi5 power supply directly to the RPi5 pcb, right? You doesn't use a additional case or gadget like RemotePi board ?

  • RPi5 with three TV tuners

    This doesn't looking good regarding the USB power. Was this an attempt with the powered HUB?

  • Remote Install OS

    And now the important question: What do you have detached? Only the Rii X8, ore more devices?

    Quote from ian_j

    I don't have a keyboard connected.

    but

    Quote from ian_j

    And my wife uses an Rii X8 for iPlayer searches

    It sounds weird to me, because the Rii X8 is a keyboard. Or do you use the RPi in time-sharing with your wife? ;)

    Perhaps you has only Caps-Lock enabled or a battery issue with that device. If somebody else have the same issue in the future, it would be nice to know.

  • LibreELEC 12.0 on Raspberry Pi5

    Only to be sure, do you use a case for your RPi5 like the Argon ONE V3? I'm asking because this case doesn't pass-through the PD information to the RPi5. The case pcb is self a power sink and negotiates the power consumption with the power supply. But the connection RPi5 <-> case pcb doesn't negotiate via PD (power delivery).
    The RPi5 relies on that power delivery information, to enable the whole 5A current and additional the USB boot support/max. USB current.

    In such case, you need to add this lines to bootloader config /EEPROM:
    PSU_MAX_CURRENT=5000

    and to your config.txt:
    usb_max_current_enable=1

  • Only 6.1 LPCM for 7.1 sources with Raspberry Pi

    Thank you for providing the additional image.

    Only for sureness, I have tested with different KODI LPCM audio and video sample files: https://kodi.wiki/view/Samples

    With the official 12.0.0 image the mapping was wrong (6.1 -> RC)

    and after update to the image with the patch provided by you it's now correct 7.1 (RLC/RRC):

  • Only 6.1 LPCM for 7.1 sources with Raspberry Pi

    Hi HiassofT , chewitt ,

    thank for your both comments/doings. Yesterday night I tested just for a short time window with the sample multichannel FLAC files. But there was some strange behavior, which has looked like the issues that _marklam_ reported.
    Yes, I prefer the passthrough way too. My RPi4 and my AVR are able to support that. But the current use case of multichannel FLAC (7.1 LPCM) files differs a little bit. I’m interpreting this as the only available way to get („passthrough“) the multichannel audio lossless to the speakers.

    chewitt
    I will try the image you provided and give you a feedback. It would be nice, if _marklam_ will test it with real music files and hopefully can confirm that it‘s working now. :)

    EDIT:
    The image chewitt has provided is for RPi2/3 only, so I can't test it with my RPi4. _marklam_ it's now your turn. ;)

  • Only 6.1 LPCM for 7.1 sources with Raspberry Pi

    Hi chewitt ,

    thank you for the clarifying. But currenly I'm little bit confused and get a node in my head. Do you have a perhaps a link to a sketch about the different positioning of SL/SR vs. BL/BR vs. BLOC/BROC speakers please?

    I'm asking because my DENON 3808 AVR reports this setup via HDMI (EDID decode) and thinking the SONY AVR of _marklam_ behaves the same :

    Code
     Speaker Allocation Data Block:
   FL/FR - Front Left/Right
   LFE1 - Low Frequency Effects 1
   FC - Front Center
   BL/BR - Back Left/Right
   BC - Back Center
   RLC/RRC - Rear Left/Right of Center (Deprecated)

    This 7.1 AVR has 6 terminals for 2x Surround A + 2x optional Surround B and additional 2x Surround Back Left/Right speakers. The Surround A terminals should be used for a 5.1 setup and the speakers placed sideways or little bit behind of the main seating.

    Currently I think BL/BR is mapped to Surround A + B and RLC/RRC is virtual in 5.1 mode. Because I currently haven't a 7.1 speaker setup I can only relies on the reported input signal.

    In that sketch for the 7.1 speaker setup example, it looks to me
    https://www.intel.com/content/dam/support/us/en/images/mini-pcs/7.1.jpg

    • that BL/BR is moved to my assumed RLC/RRC position
    • and SL/SR replaces my assumed BL/BR position

    During my research I found this kind of adapters too: https://www.allaboutadapters.com/au-hcp2.html I'cant see a different positioning for SL/SR vs. BL/BR

    I'm wonder if AESinkALSA should doing the same with LPCM 7.1 media files?

    • map media SL/SR -> HDMI BL/BR channel
    • map media BL/BR -> HDMI RLC /RRC channel

    Being I'm totally wrong with that idea? Or does all others 7.1 receivers advertise SL/SR via HDMI additional?

    EDIT:

      HiassofT Could it be that there is already an option for that, but a condition is wrong (channel replacement looks not executed) :?:

    It looks to me that the speakers that are requested not matching the speaker setup reported by your amp. The channels SL and SR are not listed by your amplifier.

    I have seen in the manual of the amplifier, that it supports different speaker schemes. How many and which type of speakers do you have? Maybe you should ensure to set it to 3/4.1 and try it again.

    Edit: Some minutes ago I have looked into my kodi.log. With my receiver I get also BLOC and BROC instead of SL/SR reported. I will test it tomorrow with that files if I come to the same result like you:

  • Only 6.1 LPCM for 7.1 sources with Raspberry Pi

    Can you please more specific?

    - which RPi? 1, 2, 3, 4, 5 ?
    - which LE version?

    The best way to provide the needed details is to enable debug logging (Settings → System → Logging), reboot and paste here the link to the log only:
    https://wiki.libreelec.tv/support/log-files

    If you currently use LE 11.0.6 or earlier, please try a current nightly - because there was important changes regarding EDID data. EDID data is the source for the audio channel information and must be correct.

  • [RPi5] Problem with HiFiBerry DAC

    Hi Lotte,

    nice, that you found a solution.

    If you currently doesn‘t have a dtoverlay=hifiberry … line in your config it seems that the overlay was instead loaded from the HAT EEPROM. Please keep in mind, that in future kernel versions it could be possible that this overlay in the HAT EEPROM will be outdated. Then you will need a matching dtoverlay line for your hifiberry.

    Regards,

    Harry

  • [RPi5] Problem with HiFiBerry DAC

    Because of this:
    Configuring Linux 4.x or higher | HiFiBerry
    HiFiBerry sound cards on the Pi5 | HiFiBerry
    Changes in HiFiBerry drivers | HiFiBerry

    you should ensure that this line is commented out:
    dtparam=audio=on
    to
    dtparam=audio=off or #dtparam=audio=on

    I had read that this command
    force_eeprom_read=0
    is deprecated, you should instead move this 2 lines to the very beginning of the config.txt

    Code
    dtoverlay=
dtoverlay=hifiberry-dacplushd

    The first line prevents it from loading the overlay out of the HAT EEPROM (hifiberry).

    I know that some users with RPi5 and a Argon ONE case use successful the hifiberry driver set with their new BLSTR DAC modules. But the driver for dacplushd could have his own bugs.
