Limitations of the LynxTWO/L22/AES16 driver of OSS
The OSS driver for the LynxTWO/L22/AES16 audio cards by Lynx Studio Technology
is based on the same driver core (HAL) that is used also by the Windows and Mac
drivers for these devices. So in general the OSS driver has the same
functionality than the Windows and Mac drivers. The control panel (ossxmix)
screens are rather similar than the Windows and Mac ones. There is no OSS
specific user documentation available for these devices but the Windows/Mac
documentation is valid for OSS too.
However the OSS driver doesn't implement all the features of these devices.
More features can be added to the driver on contract. Please check that
the features you will need are available before purchasing the driver.
The current OSS driver has the following limitations:
Unlike other parts of OSS the LynxTWO/AES16 driver is not in open source.
The driver will only be included in the precompiled binary packages distributed
by 4Front Technologies.
However we will give the source code to the customers who have signed NDA
with Lynx Studio Technology.
Only of a subset of the control panel settings are supported. The
"adapter" page lacks half of the settings. The "outputs" page provides
only 2 sources (the Win/Mac version has 4 of them).
The AES16e (PCI-E) model is not supported. At least not yet.
The Aurora16 converter is not supported in 64 bit systems. It may work under 32
bits but this has not been verified.
The HAL library used by OSS may be older version. In general we update to
the latest HAL every 1 to 3 years. This means that latest firmware versions
may not necessarily be compatible with OSS.
At this moment the LynxTWO/AES16 driver is only available for Linux (x86 and
x86_64) and Solaris/OpenSolaris (x86).
There are known issues with PC chipsets that are not properly supported by
the Linux kernel. Interrupts may fail to work in systems that don't have
native APIC driver in the kernel. This has been a problem with the intel 945
chipset (may have been fixed in the latest Linux kernels).
There have been unsolvable problems with some Linux distributions while the
same OSS/lynxtwo version works just fine under some other distributions.
