Sound issues on MorphOS and SAM460LE
  • Just looking around

    I know it is not officially supported board but maybe someone has a solution. My issue is although I had success installing MorphOS since ver 3.17 I never managed to get sound output and tried multiple cards in Pcie slot. Sound works fine in AmigaOS. It is something to do with PCI bus in this motherboard and morphOS. I was hoping the issue would be solved with new release but unfortunately it is still there. Maybe there is a custom install for SAM460LE. Any suggestions are welcome.

    @Isensei
    All Sam460LE has the same problem -look here:https://morph.zone/modules/newbb_plus/viewtopic.php?topic_id=13719&forum=53#160239
    CMI8738 and Envy24HT chips are in real PCI. So the PCIe versions of such cards had PCIe-to-PCI bridge on board. And MorphOS not see behind this bridge - look to post #17 from link above.

    You have to wait, if MorphOS team will fix it in some update. And like workaround you can use USB sound device.

    There is other possible option, if you are using only MorphOS, not AmigaOS:
    - PCI slot: sound card
    - PCIe x1 slot: SiI3132 SATAII card.
    - with this combination you have to place boot-sam460.img to SDcard and boot from it.
    Unfortunately this combination NOT WORKS for me, even if SiI3132 is MorphOS supported. I tested one PCIe SiI3132 adapter and it not worked neither in Powermac G5, neither in Sam460LE. I don't know, if my adapter was bad, or there is other reason. I also asked here on forum, if somebody successfuly use SiI3132, with no answer.

    Isn't SIL3132 more of a PCI thing? In the sense that PCIe version might also be PCI chips hiding behind such a bridge?

    No, it is pure PCIe chip. But not worked for me also in Quad, so maybe this adapter is corrupted somehow. I have no other to test. And I am too lazy test it in PC ;-)

    Hoping for the next release of MorphOS to fix it.
