Though it is always possible to be a bug in mplayer or in any other place other than oss4, the thing is that mplayer is not the only victim. The same behavior can be observed in other players(xine,vlc and amarok(with xine or gstreamer backend) for example) in different linux distros(opensuse,kubuntu, arch linux) with different versions of dbus, libpulse, kernel and media players. I have been using this card for almost two years and nothing changed through all the updates I have done so far... Besides, the problem with messed up channels that I mentioned in the last post also happens in ossplay...

I could try to compile Mplayer-vaapi... But I'm a nvidia owner happy with vdpau(and with my current Mplayer version too), is there any advantage in moving to vaapi? Is it capable of using a nvidia card for accelerated decoding?

igorzwx: right, ossplay -R wouldn't have worked. I think it's not a player bug, but a driver one though...

wwmm: I seem to forget too much stuff today - yes, you can remap the channels using 'vmixctl remap' command in OSS (see "vmixctl" manpage). Not entirely sure about commandline though - you'd have to experiment a bit (and vmix would have to be set to Multich before running 'sudo vmixctl remap 0 0 ...' etc.).

The reason you're always having this when vmix is set to Multich is that vmix (the virtual mixer) opens the device at the maximum allowed channels (or stereo - depending on vmix0-channels setting), and than mixes in the programs' output***. In your case, the maximum allowed channels are 6 - So every stereo program ends up talking to the device in 6ch, triggering this issue... Anyhow, possibly patching the driver might help. Here's a guess:

Code: Select all: diff -r 232d0de71550 kernel/drv/oss_envy24ht/oss_envy24ht.c --- a/kernel/drv/oss_envy24ht/oss_envy24ht.c Tue Nov 02 23:45:15 2010 +0200 +++ b/kernel/drv/oss_envy24ht/oss_envy24ht.c Wed Dec 29 20:44:35 2010 +0200 @@ -1367,8 +1367,8 @@ if (portc->channels == 6) { /* The fragment size must be a multiple of 6 */ - audio_engines[dev]->min_block = 4 * 288; - audio_engines[dev]->max_block = 4 * 288; + audio_engines[dev]->min_block = 4 * 1023; + audio_engines[dev]->max_block = 4 * 1023; } else

Since you're already using a version from mercurial, I assume you already know how to build OSS (see this if not). Perhaps you noticed '--only-drv=oss_envy24ht,...' '--enable-libsalsa=NO' and '--config-midi=NO' args to configure can be used to speed up compile.

*** This is necessary: think of the scenario where vmix opened the device in stereo, but allowed multich programs. Say several stereo programs are playing to the device, and then a new multich program is started. vmix would have had to either refuse the program (but the premise was we allow this), or reconfigure the device (which would probably hurt or at least suspend the playback of the existing stereo programs).

I am not a specialist in vaapi, but it seems to accelerate everything.

Do you need PKGBUILD? There is also a ready package (i686).

igorzwx: it is not necessary to give me a package build

cesium: After applying your patch ossplay and Mplayer became uncapable of playing 6 channels files(vmix is disabled). In ossplay happend the following:

Code: Select all: [wallace@wwmm surround]$ ossplay chan-id.wav audio write: Input/output error

and in dmesg:

Code: Select all: osscore: Output timed out (sync) on audio engine 0

In mplayer I could play 4 channels files but it freezed when I tried to play 6 channels files. In dmesg appeared the following:

Code: Select all: osscore: Output timed out on audio engine 0/'VIA Vinyl Tremor Audio front out' (count=0)

The same happens with vmix enabled

Of course, you may better try to write your own PKGBUILD. I would like to see it.

by **wwmm** » Wed Dec 29, 2010 7:39 pm

To be honest I was thinking in using the compiled package in the x86-64 repo or in compiling it modifying the abs PKGBUILD. I don't know how to write one...

It is very simple. Take the ready one and modify it how you want.

The package is enclosed. Unpack it, open terminal in the folder and run "makepkg".
ABS should be installed, of course, see:
viewtopic.php?f=3&t=3543&start=30#p15703

You have to remove libpulse

# pacman -Rd libpulse

then you can compile mplayer and other apps without PulseAudio. Otherwise, it might be compiled with PulseAudio.

To verify if the problem is in the applications or in the driver I enabled the onboard card(ALC888S) and performed again the "seek" test. The noises don't appear in the onboard card!!!

This fact allows to presume that the problem might be in the driver, but it does not prove anything.
It might be interesting to see "ossinfo -v9" of that onboard card.

EDIT: This kind of verification can hardly help to solve the problem. You may presume that noise is caused by the driver, but nobody else reported such noise. Why?

Well, a driver issue does seem the most likely, though not the only option.

To hazard a guess or two:
A) Multichannel setup isn't most common.
B) There are significant differences between envy24ht cards (see the driver source). Possibly only this specific card/setup needs a workaround only in this specific mode?

Now, it is possible that the driver is not bugged per se, but that the six ch. setup stresses the system enough so that there are underruns in some cases leading to the issue in question. It may be an old fashioned question, but is there an IRQ collusion (likely not, but the lspci output isn't detailed enough for me to know. 'lspci -v' should show this)?

There are a few shared irqs but if I understood the output correctly the soundcard is alone in the irq 20

Talking about the specific setup of this card I've been looking at its Encore webpage:
http://www.encore-usa.com/us/product/ENM232-6VIA

and its pci controller in VIA website:
http://www.via.com.tw/en/products/audio/controllers/tremor/

and in both places is stated that this card should be capable of 96 kHz sampling rate in spdout. In ossxmix I can only set it to a maximum value of 48 kHz. This is not a problem for me as I don't use spdout but indicates that a few functions of my card are not being correctly setup by oss4.

Perhaps, you are doing something wrong. If you do not know how to set sample rate in ossmix, read this:
https://wiki.archlinux.org/index.php/OSS

According to your ossinfo, you can set such rates:

Code: Select all: Native sample rates (min - max): 8000 - 192000 (8000,9600,11025,12000,16000,22050,24000,32000,44100,48000,64000,88200,96000,176400,192000)

Code: Select all: Audio devices VIA Vinyl Tremor Audio front out /dev/oss/oss_envy24ht0/pcm0 (device index 0) Legacy device /dev/dsp0 Caps: DUPLEX TRIGGER MMAP Modes: IN/OUT Out engine 1: 0/VIA Vinyl Tremor Audio front out Available for use Engine 2: 5/VIA Vinyl Tremor Audio front out (vmix) Available for use Engine 3: 6/VIA Vinyl Tremor Audio front out (vmix) Available for use Engine 4: 7/VIA Vinyl Tremor Audio front out (vmix) Available for use Engine 5: 8/VIA Vinyl Tremor Audio front out (vmix) Available for use Input formats (0x00001000): AFMT_S32_LE - 32 bit signed little endian Output formats (0x00001000): AFMT_S32_LE - 32 bit signed little endian Device handle: PCI24031412-0000:03:05.0-au01 Related mixer dev: 0 Sample rate source: 0 Preferred channel configuration: STEREO Supported number of channels (min - max): 2 - 6 Native sample rates (min - max): 8000 - 192000 (8000,9600,11025,12000,16000,22050,24000,32000,44100,48000,64000,88200,96000,176400,192000)

No, I'm not doing something wrong. My ossinfo output can't be right because the specs in the card pci controller website(see my last post) states that its upper limits in sampling rates are 48 khz for analog signal and 96 kHz for digital signal(the same was written in the card's box when I bought it). As the arch wiki states in envy24 cards the analog signal sampling rate is setup in the variable envy24.rate that in my ossxmix stops in 48 kHz, in accord with the specs in the website. The other instructions in arch wiki are related to the vmix sampling rate and in fact I can set it set to the values in my ossinfo output, but as soon as I play something in a sampling rate higher than 48 khz the value showed in ossxmix instantly decrease to 48 kHz(this behavior makes sense when we look at the card's specs, this is the maximum rate value for analog signals). The configuration problem is in the spdout.rate that stops in 48 kHz when it should go up to 96 kHz.

The question is, why is my ossinfo output showing sampling rates values that are not supported by the card?
