AmigaOS 4: Version 6.8 des Audio-Treibers für Intel HD Audio
An update of the new AHI driver for AmigaOS 4 has been released (amiga-news.de reported) which includes the following changes:
- Output options added (ALL, Line, Front HP, S/PDIF)
- Added support for S/PDIF output (both RCA and optical)
- Added support for output muting (mutes Line, Front HP and S/PDIF)
- Added support for line-in and microphone preamplifier. (From the CODEC perspective, Line-In and MIC are equivalent. Therefore, preamps can also be enabled for Line-In).
- Speed improvements
- Small bug fixes
Explaining, the developer adds:
"With AHIRecord you can select a monitor output. This is a strange implementation becauseese actually makes an AHI request to change the playback output. This would require a digital loop. But this is not implemented in AHIrecord.
Now that the playback output selection is implemented, this is how you control the playback output for the next playback cycle. So be careful.
The internal monitor hardware provides an analog loopback to a small selection of outputs. The Sound Blaster Audigy FX is limited to the Front HP and Line outputs.
The CM8828+CM9882 cards are limited to the Line output only. So you cannot use the HD audio front panel output as a monitor output
AHI has no way to switch to monitor input. Only to monitor volume. So all monitor outputs are enabled. But if there is a need for a single monitor output, I can add a mute option for the other single outputs."
Supported Soundcards:
- Creative Labs Soundblaster Audigy FX (24bit/192kHz 5.1)
- Startech PEXSOUND7CH (24bit/192kHz 7.1) -> available under many different names
- Fransande 411944 (24bit/192kHz 7.1) -> available under many different names
- Terratec AUREON 7.1 PCIe (24bit/192kHz 7.1)
Sound cards that should work:
- Basically any combination of HDaudio controller and HD Audio multichannel codec (e.g. CA0113, CM8828, CM9882A ALC898 etc.)
Sound cards that do not work (yet):
- Asus Xonar Phoebus solo (CM8888 in combination with Discrete DACs in high quality)
- Powercolor Devil HDX (CM8888 in combination mit Discrete DAC)
Sound cards that will never work:
- "Sound Core3D" (CA0132) based sound blasters (Eg. Z, AE-5, AE-7, AE-9 etc). These cards have a DSP (ca0132) instead of an audio codec. They initially appear to be HD audio cards but after the DSP is booted they behave totally differently. Therefore, such cards must be supported with other drivers.
- PCIe Asus sound cards that are currently on sale. These cards are either AV100 (converted CMI8788), CM8786 or C-media 6632AX (USB chip) based. None of these chips comply with the Intel HD Audio standard.
- Sound Blaster Audigy RX and all other EMU-based or X-FI-based sound blasters. (do not comply with the Intel HD Audio Standard).
- Non-PCIe sound cards in general like external USB cards or old PCI cards.
