OpenAL on Raspbian gives garbled output #359

Open righthalfplane opened 5 years ago

righthalfplane commented 5 years ago

When I run my SDR on the latest version of Raspbian, I get a garbled auto output from OpenAL that is just barely understandable. When I run a simple example, that should give a simple sine wave - I get a sound of about the right frequency, but modulated with a low roar. I am doing output through html to the speakers on the monitor. Any ideas as to what the problem is ?

kcat commented 5 years ago

Is it using PulseAudio or ALSA? How is the device configured (stereo, 5.1, etc)? Can you provide a trace log (set the ALSOFT_LOGLEVEL env var to3` when you run the app, and it'll log to stderr)?

righthalfplane commented 5 years ago

I finally found a work around for the problem. Using "alsoft.conf" I tried all of the backends - only "oss" worked with a problem. PulseAudio and ALSA had the garbled auto. PortAudio seem to work- after giving many lines of error messages. All the other options failed.

Opps - "oss" worked without a problem.

kcat commented 4 years ago

I'll need to see a trace log. Preferably when using PulseAudio, ALSA, and OSS, to see what it's doing for each and compare with the working OSS output.

This was on a new install - it give garbled output with no local config file. It does not do what it did last time.

kcat commented 4 years ago

A bit late on this, sorry about that. The only difference I can see is that the garbled output uses 3 buffer periods, whereas the ones that are okay use 4. That suggests to me it's having trouble keeping up with the device and is constantly underrunning.

If that's the case, you can try setting the rt-prio config option to 1 to enable real-time processing on the mixing thread (current master enables this by default). Ideally the kernel would boost the priority of the mixing thread automatically since it spends most of the time sleeping, but low power devices that throttle the cpu speed seems to interfere.

One of TDM users had similar problem. See original discussion on TDM forums.

He says everything works properly with period_size = 64 and with period_size = 8192 (except for a huge delay of course), but intermediate values from 1024 to 4096 cause stuttering noises. Setting rt-prio = 1 does not help.

Currently TDM uses version 1.19.1 of OpenAL.

kcat commented 3 years ago

I wonder if there's something going on with Linux's CPU scheduler or power management. A period size of 64 working but not 1024 doesn't make much sense, since the latter is giving the system more time to actually process the audio. At 48khz, a period size of 64 means the mixer thread needs to wake up every 1.3 milliseconds to mix audio. If their system can keep up with that, I fail to see why a period size of 1024, which has the mixer thread wake up every 21.3ms, would suddenly be a problem. The only thing I can think of is that with 1024~4096, the mixing thread being asleep that much causes the CPU to go into a reduced power mode that causes wakeups to be significantly delayed, while lower values keeps the CPU more active and responsive. Though that's generally more an issue with mobile/laptop cpus than desktop.

Anecdotally, I recently upgraded my desktop system from an ancient dual-core CPU to a Ryzen 5 3600 and found JACK was completely hosed. While it was fine on my old system, the sound with JACK on my new system would be completely out or skip heavily, and it would constantly underrun despite not doing anything demanding. At the same time, PulseAudio plays fine but has a much higher level of latency than with my older system. Interestingly, ALSA seems to work fine when using direct hardware devices (can't really test dmix at the moment).

Being able to see their OpenAL log would be helpful, as would testing the latest version (1.21, if not current git). They should be able to get a log with something similar to what you suggested in the forums. Starting in a command shell from the directory with the executable, run:

export ALSOFT_LOGLEVEL=3
export ALSOFT_LOGFILE=openal_log.txt
./the_command

or alternatively, all on one line:

ALSOFT_LOGLEVEL=3 ALSOFT_LOGFILE=openal_log.txt ./the_command

Perhaps it is the issue of Doom 3 engine. It also has a separate sound thread. Originally it was doing the mixing, but now it just streams data into OpenAL buffers. Its Linux code is pretty weird:

THREAD_RETURN_TYPE Sys_AsyncThread(void*) {
    int now;
    int next;
    int want_sleep;

    // multi tick compensate for poor schedulers (Linux 2.4)
    int ticked, to_ticked;
    now = Sys_Milliseconds();       //returns int32_t milliseconds, obtained via gettimeofday
    ticked = now >> 4;
    while (1) {
        // sleep
        now = Sys_Milliseconds();
        next = ( now & 0xFFFFFFF0 ) + 0x10;
        want_sleep = ( next-now-1 ) * 1000;
        if ( want_sleep > 0 ) {
            usleep( want_sleep ); // sleep 1ms less than true target
        }

        // compensate if we slept too long
        now = Sys_Milliseconds();
        to_ticked = now >> 4;

        while ( ticked < to_ticked ) {
            common->Async();    //sound mixing happens here
            ticked++;
        }

        // thread exit
        if (asyncThreadShutdown)
            break;
    }

The sound streaming code writes to three OpenAL buffers in cyclic fashion (typical triple-buffering), each buffer has size MIXBUFFER_SAMPLES = 4096 samples. I believe sound data is always pushed at 44100 Hz frequency.

Hi. Here is the OpenAL log with ALSOFT_LOGLEVEL=3 ALSOFT_LOGFILE=openal_log.txt when running The Dark Mod (64bit engine). Generated with period_size = 1024 in alsoft.conf: I normally use 64 which prevents me from getting the issue... the higher this value the more likely it is to encounter the problem, 1024 is where it's bound to trigger it half the time.

openal_log.txt

As I explained on the TDM forum: The broken sound lasts for some 1 to 30 seconds, during which I hear all audio in interruptions and the game lags with decreased FPS. Once this amount of time passes everything's normal again, but sometimes you need to wait a bit. It feels like something overloads the audio system at startup and you need to wait until it catches up.

kcat commented 3 years ago

Do you have PulseAudio installed? Your libopenal doesn't seem to be built with PulseAudio support, so if you use it, it will be using the ALSA->PulseAudio bridge, which could account for some of the issues (if playback is regularly underrunning, it'll increase the latency over time to compensate). If not, how well does it work when using a device other than ALSA Default?

MirceaKitsune commented 3 years ago

I use the libraries installed by my distribution, which is openSUSE Tumbleweed x64. I tried using other listed devices but always get no sound if I do.
