[Bug 996906] Re: periodic audio skips with Intel HDA
I have the same problem : sound stops after undeterministic time: from several minutes to more than 12 hours. I'm on a raspberry pi (wheezy raspbian). I tried many combinations of parameters for daemon .conf and default.pa. I notice that whenever i change the parameters , most of the time the new parameters are not taken into account even after pulseaudio -k and pulseaudio --start, i have to restart my "player" which is chromium and sometimes it even seemed that the change was only effective after a reboot of the RPi. By the way pacmd alsa-sinks says that the buffer size and fragment size are equal for my RPi sink !! how can that be... so i have no idea what parameter to give to the daemon given that puklseaudio does not accept number of fragments = 1 (?!) i'm currently running with : number of fragments =10 and fragment size = 10 ms because people adviced to use this on forum but i really dont understand where these numbers come from and if these are a good choice -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/996906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

New sound card, same issue. Asus Xonar DX. Shows up in lspci like 'C-Media Electronics Inc CMI8788 [Oxygen HD Audio]'. Uses the snd_virtuoso driver. The snd_hda_intel module isn't even loaded. The skips have slightly changed character with the new card, but they still happen. And still, when I use bare Alsa, the issue goes away. Looks like the bug is somewhere in how pulse interacts with my machine in general, not just the sound card/driver. Raymond: I don't know. I haven't set any latency myself.

I finally upgraded to 14.04; same exact issue. One coincidence I noticed and am looking into is that I didn't notice any stuttering when only 64 bit code was running, but when flash or steam were running (both of which run some 32 bit code, if I'm not mistaken), the stuttering began immediately. I'm not 100% sure that's the only time it stutters now, but it's happened enough times that I'm not sure it's just coincidence. Does that ring any bells for anyone? I'm sick and tired of this issue. Ubuntu has moved on from Alsa, and I'd like to too. I might get a (hopefully cheap) sound card to test out if that can fix the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/996906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here's my current incantation which seems to work for me: 1. In /etc/modprobe.d/alsa-base.conf have a line: options snd-hda-intel enable_msi=0 2. In /etc/pulse/default.pa I have: .ifexists module-udev-detect.so load-module module-udev-detect tsched=0 .else ### Use the static hardware detection module (for systems that lack udev/hal support) load-module module-detect tsched=0 .endif 3. Not sure if relevant, but this a change in /etc/pulse/daemon.conf: default-fragments = 256 default-fragment-size-msec = 4 4. Important, I fire up alsamixer and set Auto-Mute to Disabled. If one of these steps is missing the problem is bad. With these, the stuttering is rare. And no, I won't rant about how playing audio on BeOS was so unproblematic.

I'm experiencing the same behavior as berend in post #22. My Bluetooth headphones work great, but the HDA Intel device in my Lenovo ThinkPad T420 gives me fits. My solution for right now is to use an external USB audio device or Bluetooth headphones to work around the problem. It's interesting that so many people could potentially be affected by an issue affecting the HDA Intel hardware, yet this thread is quite small. There's got to be a specific combination of hardware and software that causes this issue. At this point I guess we know that snd-hda-intel and pulseaudio are required to reproduce the issue.

[Bug 996906] Re: periodic audio skips with Intel HDA
Like I said above, mine now skips much less frequently than every 10 minutes, so I'm skeptical about tweaking any pulse configs at this point. And since all I did to have it skip less frequently was re- install pulseaudio and update to all the latest precise packages, it seems like the issue is somewhere in the interaction between pulse and the kernel or hardware or the system in general. If there's a way I can test using the "wakeup_rt tracer" I'm happy to do so. Is there any documentation I can read about doing so?

[Bug 996906] Re: periodic audio skips with Intel HDA
So on ubuntu precise I have spent a ton of time playing with my pulseaudio settings and system. I have the skips down to about one every ten minutes or so, and humorously while I was typing this sentence. I have tsched=0 but in regards to Raymond, my default-fragment-size-msec = 4 default-fragments = 8 and my flash videos in chrome play great. My mind is weak in the morning before coffee, but I remember that chrome was requesting buffers of size on the order of 64 - 100 ms , somewhere in there. I might be incorrect, but I believe I needed my pulse settings to be LESS than that. So 4 * 8 is 32 ms. Also, you can check ( with pacmd list-sinks ) that with tsched=1, I noticed that the "current latency" starts at like 2 ms, and as it skips, gets larger, mine would get to around 32 - 64 ms . in /etc/modules i have options snd_hda_intel bdl_pos_adj=32 power_save=0 power_save_controller=N model=6stack-dig but you'll have to figure out your model if you use that param here is some of my pulse settings for you to try cat /etc/pulse/daemon.conf | grep -v -e "^;" -e "^#" | sed '/^$/d' allow-module-loading = yes allow-exit = yes high-priority = yes nice-level = -20 realtime-scheduling = yes realtime-priority = 99 exit-idle-time = 1 scache-idle-time = 1 log-target = auto log-level = error resample-method = speex-float-8 enable-remixing = yes flat-volumes = no rlimit-nofile = -1 rlimit-nice = -1 rlimit-rtprio = -1 rlimit-rttime = -1 default-sample-rate = 44100 default-sample-channels = 2 default-channel-map = front-left,front-right default-fragments = 8 default-fragment-size-msec = 4 and here is some more output pacmd list-sinks * index: 0 name: driver: flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY state: RUNNING suspend cause: priority: 9959 volume: 0: 100% 1: 100% 0: 0.00 dB 1: 0.00 dB balance 0.00 base volume: 93% -2.00 dB volume steps: 65537 muted: no current latency: 31.85 ms max request: 5 KiB max rewind: 5 KiB monitor source: 0 sample spec: s16le 2ch 44100Hz channel map: front-left,front-right Stereo used by: 1 linked by: 1 fixed latency: 31.93 ms card: 0 module: 4 properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "ALC889 Analog" alsa.id = "ALC889 Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel" alsa.long_card_name = "HDA Intel at 0xf312 irq 50" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-:00:1b.0" sysfs.path = "/devices/pci:00/:00:1b.0/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.name = "5 Series/3400 Series Chipset High Definition Audio" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "5632" device.buffering.fragment_size = "704" device.access_mode = "mmap" device.profile.name = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Built-in Audio Analog Stereo" alsa.mixer_name = "Realtek ALC889" alsa.components = "HDA:10ec0889,80860032,0014" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" ports: analog-output: Analog Output (priority 9900, available: unknown) properties: active port: -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/996906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Results: using "options snd-hda-intel position_fix=1" in /etc/modprobe.d /alsa-base.conf didn't make the problem go away. Using position_fix=2 made the problem actively worse: the audio literally didn't do anything but skip. Using "load-module module-udev-detect tsched=0" in /etc/pulse/default.pa made flash videos unplayable (not just the audio, but the video would stutter as well).

I've been trying to reproduce this issue for the last couple weeks, and I'm somewhat happy to say it happens much, much less frequently now. Unfortunately, it still happens. It's now on the order of once every few hours on average instead of once every few minutes, but much less regularly -- only one afternoon has it happened more than once as I've been listening to music, and that afternoon it happened 3 or 4 times. I'm on pulseaudio 1:1.1-0ubuntu15.1 and kernel 3.2.0-32-generic now. Anyway, that's made it much harder to test any fixes.
