jackd with hdaudio

[adamk]

Is this possible?

Simply running 'jackd -d oss' gives me:

Various options get me further, but they all bomb out as soon as a jack client tries to connect.

This guy managed to get jackd running on FreeBSD using the '-b' switch. Maybe this will help you too?

If that method fails for you, I have a few more ideas:
A. Set vmix0-src to OFF in ossxmix, so no sample conversion is done, and try again.
B. Try using portaudio backend, which should also work with OSS.
C. Upgrade to OSS v4.1-rc2 (or latest source from mercurial) using this guide and see if jackd works better there. There have been a few enhancements to freebsd support not in 4.0 b1016. In particular, /dev/dsp can now support multiple clients, just like the native system (This requires a FreeBSD version which is probably slightly newer than the one you're using [edit: I was referring to the functionality - not OSS itself which still supports older FreeBSD like FreeBSD 6]).

[adamk]

I will have to give option C a try when I get a chance. Using -b didn't change anything, setting vmix0-src to off didn't either. And using the portaudio backend gave me:

Hi,

Try using the "-n" switch together with the portaudio backend: "jackd -d portaudio -n oss" or something like that.
As for newer OSS 4.1, it checks for _FreeBSD_version >= 700111 **, so FreeBSD 7-STABLE, 7.1-BETA, and the FreeBSD version used in PCBSD 7 should all be fine. That said, you do not need to upgrade to install it - it will still work on your system (or on FreeBSD 6 for that matter). Using a newer FreeBSD just enables additional functionality (multiple clients for /dev/dsp), which is not neccesarily helpful for your problem.

** This value is defined at /usr/include/sys/param.h

[adamk]

'jackd -d portaudio -n oss' gives the same error as just 'jackd -d portaudio'. I should have a chance later today to try a newer version of oss. One of my machines is already at 700112, and I'm upgrading the other now since I could really use the ability to have multiple clients access /dev/dsp

Thoughts?

[cesium]

Drat. I didn't know that FreeBSD doesn't have that, especially since the manpage mentiones it... Just edit the file, and remove the (error != ENONET) comparison. [edit: Actually, the problem was me being an idiot and missing a spelling error]

[adamk]

Well it builds now

Unfortunately, I still get this error when using -d oss:

jackd does work on another machine with an ich chipset (both with 4.0 and 4.1-rc2). Interestingly, though, the ich chipset does not allow multiple apps to access /dev/dsp, though, even with 4.1-rc2. The second mplayer instance gives me:

[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device busy

And, finally, just a few general observations about 4.1-rc2... I really don't like the idea of packages installing under /usr, which is what happens when you pkg_add the results of 'make package'. And why is oss getting loaded if oss_enable is set to "NO" in /etc/rc.conf ?

Adam

[cesium]

Well it builds now

Unfortunately, I still get this error when using -d oss:

OSS: read() failed: oss_driver.c@1068, count=-1/4096, errno=13

Does recording work in general with the hdaudio machine? Also try "jackd -d oss -i 0".

Interestingly, though, the ich chipset does not allow multiple apps to access /dev/dsp, though, even with 4.1-rc2.

Probably vmix is not attached to /dev/dsp for some reason? Do "vmixctl attach /dev/dsp" (as root), and it should work.

And, finally, just a few general observations about 4.1-rc2... I really don't like the idea of packages installing under /usr, which is what happens when you pkg_add the results of 'make package'. And why is oss getting loaded if oss_enable is set to "NO" in /etc/rc.conf ?

The package generated by the build system isn't integrated all that well into FreeBSD (and OSSv4.0 had the same issue). You probably had the ports package "audio/oss" installed earlier which is integrated well. This is partly because most people here use Linux/Solaris and don't understand FreeBSD conventions, and partly because rather little feedback is given for OSSv4 on FreeBSD platform so stuff like ENOENT issue get through... Fixing this at least partially should be quite doable (e.g. most stuff looks in /etc/oss.conf to get base directory anyway so changing it to be under /usr/local is easy).

[adamk]

Actually, I couldn't care less about recording at the moment I never realized that setting the input channels to 0 would disable recording entirely. I am, thankfully, not getting the "OSS: read() failed" error, but mplayer is hanging when trying to connect as a jack client:

Code: Select all

AO: [jack] 48000Hz 2ch floatle (4 bytes per sample)
Video: no video
Starting playback...
A:  -0.0 (unknown) of 253.0 (04:13.0) ??,?%


And it just hangs there.

Something odd is going on with the other machine (the one where vmix was giving me problems). I'm going to try a few things and if I still have problems with it, I'll start a new thread

Adam

[cesium]

Can you test with another jack client? This will help find out if its mplayer's fault or not. Also, perhaps using "-vv" with jackd will give more output...

[dev]

Under FreeBSD you have to specify JackD with separate input and output devices since VMIX doesn't automatically handle full duplex.

[adamk]

audcious, with the jack plugin, displays the same problem. Interestingly enough, it works fine with my ich chipset at work, but not this HDA chipset or an SB Live! Value that I threw in to test with. The Live! shows the exact same problem. jackd will start, but connections just hang.

You can see jackd exiting when I hit control-c.

This is with the hda sound card and the hdaudio driver.

I'm start jackd like so: 'jackd -vv -d oss -i0'

What happens if you disable vmix entirely? (Add "vmix_disabled=1" to /usr/lib/oss/conf/osscore.conf)

[adamk]

Same problem, unfortunately.
