The latest support Intel HDA is 0x8c20, and I am using a348. If your sound card is not listed there, it is not supported.

• 8c20 ("8 Series/C220 Series Chipset High Definition Audio Controller")
• a348 ("Cannon Lake PCH cAVS")

Kernel 5.9.10 has brought another error. Now the package is built as usual without problems and after executing the "soundon" command the module itself is also built without problems (and it does exist in "extramodules/oss" directory). But after the "soundon" command the following output is produced:

Relinking OSS kernel modules for ""
This may take few moments - please stand by...
Relinking OSS kernel modules finished
SNDCTL_SYSINFO: Inappropriate ioctl for device
SNDCTL_SYSINFO: Inappropriate ioctl for device

OSS started OK

But in reality the sound output does not work. It's impossible to execute even the "osstest" command. That command produces the same error "SNDCTL_SYSINFO: Inappropriate ioctl for device".

@Next7 Amended patch. Had to add two back slashes for one to appear on this board.

@seawright

Many thanks again. Now module is built and works but it's important to watch out misspelling in the patch probably caused by the board's formatting rules: "$N_" should be "$N\_".

@Next7 I have seen this message before, "/usr/lib/oss/build/.osscore_mainline.o.cmd: No such file or directory", though before Linux kernel version 5.8 it had never prevented the OSS kernel modules from being built. I always assumed it to be a warning though it now appears to be an error. The following patch should clear it but I would expect further errors to be reported. To date I haven't managed to get sound to work with any kernel later than 5.8.0rc6 but as I'm using a patched Ubuntu kernel your experience may be different.

Module now fails to build for kernel 5.8.8. After creating directory "/usr/lib/modules/5.8.8-arch1-1/extramodules/oss" the command "soundon" produces the following output:

Relinking the OSS kernel modules failed

AFAIK any patches required to build OSS4 for Linux Kernel version 5.6.14 have been applied upstream to: git://git.code.sourceforge.net/p/opensound/git

Two problems specific to Arch remain:

1. The build will fail if /usr/lib/modules/5.6.14-arch1-1/extramodules does not exist.
2. CFLAGS in makepkg.conf may require overriding as they take precedence over the CFLAGs present in OSS4's Makefiles.

@Galaxy This was my reply to alexdw when asked a similar question. "Thank you for your offer but I feel I must decline. While I use and therefore have an interest in the ongoing development of OSS4 I do not use Arch and have little knowledge of its package build system. I hope my refusal doesn't result in the Aur OSS* packages becoming unmaintained". My feelings and my knowledge of Arch have not changed though I am always willing to assist if the problem is OSS4 related as opposed to Arch Linux or its package building tools.

@seawright Would you like to be the maintainer of this aur ?

@seawright

Huge thanks! Now everything compiles and works flawlessly. I owe you a beer or a cup of coffee! I'm serious. PM me your data on main forum for a donation.

Oh dear the mark down has really mangled the second code block.
