I just find 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")

@sliviu Is -no-pie necessary ?

It seems good to use -O2 as suggested by Gentoo make.conf. Their kernel even suggests -Os.

I cannot load the module with -no-pie, I change it to -fno-pic -fno-PIE on <https://github.com/GalaxyAUR/oss-git>.

See also <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=841368#36>.

Starting at gcc 6.2.0-7 we must provide "-fno-PIE -fno-PIC" in
beginning of CFLAGS to build kernel successfully.

If someone reports OK, I will push it here.

The /usr/bin/soundon also need to be patched. But you can just modprobe osscore anyway.

@Galaxy: Thanks - reassigned maintainer from me to you.

And yes - I also tended to follow the comments here, and on the oss forums (in particular the Linux subform) for new patches: http://ossnext.trueinstruments.com/forum/viewforum.php?f=27

@alexdw Some questions on current PKGBUILD:

1. Why configured with --enable-libsalsa=NO ? I find oss-nonfree come with libsalsa.so.2.0.0.

2. The --config-midi=NO|YES seems not enabled by default. Why not append it with "YES" ?

3. CONFIG_REGPARM=y should be available only on x86 kernels, override the automated checking with --regparm seems strange.

@alexdw I'd like to. Is this OK to follow comments here for new patches? As I am not familiar with kernel developing.

Also, I checked the oss-v4.2-build2019-src-gpl.tar.bz2 and find the code is the same as commit 7cf6b07f3256407a4b30608f0a8e55677b49942f on 2018/02/24 for "Compile fix for Linux kernel 4.15", except for some changes in devlists/FreeBSD and devlists/Solaris-sparc.

FYI, interestingly oss-nonfree works with the new version (4.2 build 2019): https://aur.archlinux.org/pkgbase/oss-nonfree

@Galaxy: Do you want to take over as maintainer of this oss-git AUR package? I see you already applied a couple of patches in your GitHub: https://github.com/GalaxyAUR/oss-git

For those who compiled with gcc 8.2.1: if the kernel ooopses on oss_hdaudio loading change to -O2, -O3 generates floating point instructions

Yes, compiled with the PKGBUILD from Galaxy.

As I said, "Compiles with some warnings". An interesting one:

 warning: In the GNU C Library, "makedev" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "makedev", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "makedev", you should undefine it after including <sys/types.h>.
       if (mknod (dev, node_m, makedev (major, minor)) == -1)
