Hello,
Have you experienced it prior to 8.99.39?
What firefox (or pkgsrc) version do you use?
What base release do you use? In other words,
8.x userland + 8.99.39 kernel or 8.99.39 userland + 8.99.39 kernel.
Thanks,

also, if I 'audiocfg list' I get errors.

Same here, latest kernel, userland from 8.99.37 (build on April 23).
Playing audio via sun audio and mpg123 seems to work fine, while firefox
and oss stutter badly.
The old userland audiocfg seems to work:
0: [*] audio0 @ hdafg1: vendor 10ec product 0670, 12 playback channels
but kernel traces:

Hi,
On freshly build NetBSD/amd64 8.99.39 (kernel+userland),
freshly installed www/firefox-66.0.5 (not committed yet)
works fine for me.
My www/firefox uses PulseAudio to play audio.
Of course PulseAudio uses OSS.

I'm having similar trouble with Youtube videos played with firefox.
The first second or so of a video plays and then everything starts
chopping and stuttering. The video doesn't really continue, seeming
to wait for the audio to get its act together.
I'm using firefox52 built with:
PKG_DEFAULT_OPTIONS+=oss -pulseaudio -alsa
My system:
amd64 8.99.39 with:

Isaki-san is currently AFK, but I have some discussion with
Y.Sugahara-san (a co-author of isaki-audio2 branch).
I'd like to summarize what's going on current audio2 kernel
and pkgsrc firefox.
- the problem is not on individual hardware driver, but
possible inconsistency between MI audio and ossaudio compat layer
- the firefox upstream droped official OSS support long ago
- pkgsrc has own patch file, patch-media_libcubeb_src_cubeb__oss.c:
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/www/firefox/patches/patch-media_libcubeb_src_cubeb__oss.c
http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/pkgsrc/www/firefox/patches/patch-media_libcubeb_src_cubeb__oss.c?rev=1.12&content-type=text/plain
- the oss support patch seems derived from FreeBSD ports:
https://github.com/freebsd/freebsd-ports/blob/cd8036681e83301a86135acd26900d1eaf495d29/www/firefox/files/patch-bug1021761
but they has also removed their local patches as "No upstream maintainer":
https://github.com/freebsd/freebsd-ports/commit/098a888c8d8ec393674d12df7494fb81efbe12d8#diff-ee613bc8b4f46e2a591162768020ab92
- firefox's cubeb_oss.c calls the following OSS ioctl's:
SNDCTL_DSP_SETFRAGMENT
SNDCTL_DSP_CHANNELS
SNDCTL_DSP_SPEED
SNDCTL_DSP_GETODELAY
SNDCTL_DSP_CURRENT_OPTR
SNDCTL_DSP_GETOPTR
and probably something wrong in GETODELAY and/or GETOPTR
- MI audio layer has proper infomation for GETODELAY,
but there is no public API to pass it to oss compat layer,
and SNDCTL_DSP_GETOPT seems to return some bogus value
- Sugahara-san says cubeb_oss.c seems to have some buggy code
(cubeb function that calls setfragment() assumes latency in millisecond
but gecko seems to assume a number of frames?)
-> there is a possibility that cubeb_oss.c is implemented for
oss layer with some bugs (or weird compatibility) and
it stops working after isaki-audio2 cleanup
I'm afraid we need to prepare some bug-compatibility code for oss
for unofficial firefox patch..

I would not worry too much about binary compaibility for a single app that
everyone *really* needs to update every other month or so.
If the problem is well understood, the bugs in cubeb_oss.c are fixed and
new binaries work fine with the new audio code, all should be fine.

It depends on the OS and they do not do a proper NetBSD release themselves,
so I would argue it is our call.

For me both pulseaudio and alsa options worked.
Possible problems are:
(1) pulseaudio
- pulseaudio defaults are not NetBSD friendly
- mmap issue (patched in pkgsrc)
http://mail-index.netbsd.org/pkgsrc-changes/2015/12/25/msg133989.html
- too much RAM via shm_open(3) due to our shm_open implementation
(uses tmpfs for shm_open(9) but pulseaudio requires 32MB for each app)
-> it would be better to disable shm (i.e. set "enable-shm = no"
in ~/.config/pulse/daemon.conf or /usr/pkg/etc/pulse/daemon.conf)
but it is not default
- annoying warning message on every startup of pulseaudio daemon
>> W: [(null)] caps.c: Normally all extra capabilities would be dropped now,
>> but that's impossible beause PulseAudio was built without capabirities
>> support.
due to lack of "capabilities" support
https://linuxjm.osdn.jp/html/LDP_man-pages/man7/capabilities.7.html
- pkgsrc pulseaudio requires spidermonkey17, but it's extremely huge
- Linux binaries that use pulseaudio (adobe-flash-player, for example)
do not work on NetBSD/amd64 (PR/50603)
- pulseaudio requires dbus daemon running (via /etc/rc.d)
(2) alsa
- alsa would be better even for NetBSD because users can choose
oss or pulseaudio in ~/.asoundrc or /etc/asound.conf
- possible problem is lack of documentation?
http://mail-index.netbsd.org/netbsd-users/2009/02/11/msg003038.html
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/audio/alsa-plugins-pulse/MESSAGE?rev=1.1&content-type=text/x-cvsweb-markup
- it also requires alsa-plugins-oss or alsa-plugins-pulse packages
but not explicitly mentioned?
Probably I have to prepare an English version of this blog page..

It's not just firefox that is broken. mpv drops frames. this breaks
audio-video synchronization.
I don't consider pulseaudio an acceptable option.

Please send another new PR about mpv.
We aren't sure yet whether these are the same problem or not.

This message will be shown if you use old audiocfg.
But it was verbose. Previous audio driver returned EINVAL silently
if the same thing happened. I should follow it.
Here is details.
In the past, there was no way that userland apps know the number of
channels of hardware driver. Then audiocfg attempted to set
channels 2, 4, 6,..., 16. This method used to work at that point.
In netbsd-8, this operation was changed to software channel and the
kernel limited it to 12 in 2017 (See also PR/52435). Therefore
audiocfg on netbsd-8 always shows 12 channels regardless of hardware.
# And trying to set 14 channels fails.
In audio2, I introduced AUDIO_QUERYFORMAT ioctl for this purpose
and new audiocfg(1) uses it to know hardware information. Then such
problems are gone.
Thanks,

Hmm.. Please send a new PR if you find details.
