[alsa-devel] Internal speaker output from Sony Vaio Z (2010 model) lost somewhere between 3.1.0 and 3.2.6
by Adam Williamson 20 Sep '12

20 Sep '12

Welp, pretty much as the topic says. I just noticed today that sound is no longer playing from the internal speakers of my laptop, a 2010 model Sony Vaio Z. Plugging in headphones causes sound to be played fine through those. There are three possible choices for 'Connector' - 'Analog Speakers', 'Analog Output', and 'Analog Headphones' - but none of these seems to make sound come out of the internal speakers. The default is 'Analog Speakers', and when it's set to this, headphone output does work when headphones are plugged in. I've verified that it's broken on Fedora 16 kernels 3.2.6-4, 3.2.8-3 and 3.2.10-1. It's also broken in a very recent Fedora 17 kernel, 3.3.0rc6 or so. It works on a Fedora 16 live image, with kernel 3.1.0-1. Unfortunately the kernels before 3.2.6 have been trashed from Fedora's buildsystem archives, I think, so it's hard to narrow things down any further :/ the alsa-info output is http://www.alsa-project.org/db/?f=368e2359757b537d4daa0f5399830d3942540196 .

So this looks reasonably familiar, int0 is DFU int1 is mixer int2 is audio out int3 is audio in int4 is midi int5 is HID Quirk should look like the fast track ultra basically. maybe the mixer is less broken in this device? Should we start with just QUIRK_STANDARD_AUDIO_INTERFACE or copy the whole data section from the Ultra quirk?

[alsa-devel] Help requested: new HSS1394 MIDI back-end
by Sean M. Pappalardo - D.J. Pegasus 01 Aug '12

01 Aug '12

Hello everyone. I am a developer for Mixxx, GPL cross-platform digital DJ software: http://www.mixxx.org. My focus is the controller subsystem. I am ready to finally add Linux support for HSS1394 DJ controllers such as Stanton's SCS.1m and SCS.1d. HSS1394 is just MIDI over IEEE1394 (Firewire) at wire speed. The Windows and OSX library source code is LGPL and available on LaunchPad here: https://launchpad.net/hss1394 The Stanton SCS.1m is a sound interface integrated with a two-way control surface that speaks HSS1394. (The sound card uses an Oxford chip set and works fine with FFADO 2.0.1 today up to 96kHz. I use it with Mixxx via JACK.) The Stanton SCS.1d is a two-way control surface (no sound card) that speaks HSS1394 and is capable of sending ALOT of latency-sensitive data: about 4000 messages per platter rotation. (Now imagine if you had four or even two of them on the same network running at +50% speed. This would quickly overwhelm USB, at least at the time these devices were designed.) Read about them here: http://www.stantondj.com/stanton-controllers-systems/system1.html After a lengthy discussion on the FFADO mailing list, we determined that the best (cleanest and most flexible) way to get Linux support for these devices is to write an ALSA kernel driver that speaks HSS1394 with the devices and presents an ALSA MIDI device (with no data rate limits) for each to Linux applications. The advantage of doing this is that the devices will appear to all MIDI applications without them having to have specific support for HSS1394. This means they could be used in DAW applications as well. (FWIW, FFADO trunk has a program called test-scs that does exactly this, but using that is impractical because it depends on various internal parts of the FFADO source so would require bundling all of FFADO with the application, and it's unable to see non-audio devices due to FFADO's intended use (so it sees the SCS.1m but not the .1d.)) So my questions are: where can I find documentation on writing a new MIDI driver for ALSA? And is anyone else interested in helping me do this? Thank you very much for your time and work. Help me take the last step to my dream DJ setup! (Linux, FLAC and SCS.1 controllers.) Sincerely, Sean M. Pappalardo "D.J. Pegasus" Mixxx Developer - Controller Specialist

[alsa-devel] Using UCM with PulseAudio
by Arun Raghavan 23 Jul '12

23 Jul '12

Hello, I've been working on porting PulseAudio to Android on the OMAP4-based Galaxy Nexus, and have recently looking at the policy-bits. The basic porting has been greatly simplified with Wei Feng's work to renew PulseAudio UCM integration and Liam's help with fixing up some of the UCM config for the Galaxy Nexus. I am, however, facing some trouble mapping how the hardware is used to how UCM presents it (or, perhaps, the UCM-PA mapping does). Some simplified background: the devices of interest on the OMAP4 SoC are the main hifi PCM which can be routed to various outputs, the modem PCM which is not used for actual output but to enable use of the modem during calls, and the tones PCM which is intended to be used for playing ringtones, aiui. The first problem is mutual exclusivity of verbs. From what I can understand, verbs are intended to be mutually exclusive -- if you have a HiFi verb and a VoiceCall verb, only one may be used at a time. We have mapped verbs to card profiles, which offer the same guarantee. However, on Android (which is a fair example of the kind of audio policy we might want), the HiFi verb PCMs maybe used while the VoiceCall PCMs are open. This is done, for example, to play an end-of-call tone from the CPU while the modem PCMs are still held open. Is there some way to do this with UCM? The second problem is having separate PCMs for modifiers. In the OMAP4 profile, ringtone playback is exposed via a PlayTone modifier which corresponds to a separate PCM from regular HiFi playback. In the UCM-PA mapping we decided on, modifiers were implemented as device intended roles on a sink, so that when a stream with that role came in, we could enable the modifier, and disable it when such a stream ends. However, this doesn't account for switching the PCM on which playback is occurring. Should we be creating a separate sink for such modifiers (with lower priority, so they're not routed to unless there's a stream with the required role coming in)? Or should we be reopening the PCM for this? Finally, a question also related to modifiers -- is it expected that there will never be a case where a stream that requires no modifier is being played while a stream that does require a modifier also exists? If not, what kind of policy should we have for enabling the modifier or not? Cheers, Arun

[alsa-devel] [PATCH 0/2] RFC: support for audio wall clock
by Pierre-Louis Bossart 21 Jul '12

21 Jul '12

V2 of patches to show how the audio wall clock (eg. the HDAudio one) can be used to provide precise audio timestamps and track the drift between audio time and system time. On my laptop I am able to track a 7ppm delta. I will explain in more details how this can be used during LPC in San Diego, but with the summer coming I'd like to get feedback as there are changes to the core/alsa-lib that haven't been modified in years. TODO: - 64-bit alignment, verification of pcm_compat.c changes - handling of digital inputs, need to disable wall-clock timestamps in that case (feedback from Clemens) - check differences in protocol - change timecounter to avoid accumulation of rounding errors in cycle->ns conversions - check overflows - rework the timecounter init on trigger Pierre-Louis Bossart (2): ALSA: core: add hooks for audio timestamps read from WALLCLOCK ALSA: hda: support for wallclock timestamps include/sound/asound.h | 7 ++++- include/sound/pcm.h | 2 + sound/core/pcm_compat.c | 13 +++++++++- sound/core/pcm_lib.c | 15 ++++++++++- sound/core/pcm_native.c | 2 + sound/pci/hda/hda_intel.c | 54 ++++++++++++++++++++++++++++++++++++++++++++- 6 files changed, 86 insertions(+), 7 deletions(-) -- 1.7.6.5

[alsa-devel] [PATCH] powerpc: select PPC_CLOCK unconditionally for FSL_SOC
by Shawn Guo 10 Jul '12

10 Jul '12

Freescale PowerPC SoCs share a number of IP blocks with Freescale ARM/IMX SoCs, FlexCAN, SSI, FEC, eSDHC, USB, etc. There are some effort consolidating those drivers to make them work for both architectures. One outstanding difference between two architectures is ARM/IMX will turn off module clocks during platform initialization for power saving and expects drivers manage clocks using clk API, while PowerPC mostly does not do that, and thus does not always build in clk API. Listing all those driver Kconfig options in "select PPC_CLOCK if" seems not scalable for long term maintenance, and could easily introduce Kconfig recursive dependency. This patch chooses to select PPC_CLOCK unconditionally for FSL_SOC to always build clk API for PowerPC in.

[alsa-devel] A problem with USB audio devices and the UHCI scheduler
by Monty Montgomery 04 Jul '12

04 Jul '12

A question for Clemens et al... Background: I can run a USB audio device at 6ch/24 bit single duplex, but I cannot run the same device at 16 bit stereo full duplex. UHCI and EHCI both say 'not enough bandwidth' (OHCI works). EHCI's scheduling issues are well known, but I was surprised UHCI could not schedule this either. The cause is simple; UHCI (and EHCI) use the endpoint's wMaxPacketSize for all bandwidth allocation. My device supports all of its sample rates on the same altset, with a wMaxPacketSize matching the highest (96kHz) rate. So, the HCD is reserving most of the USB bus's bandwidth regardless of the actual requirements. How should I approach fixing this in the driver? There's currently no means to communicate a desired bandwidth reservation to the HCD from USB audio, so I'd have to extend even the quirks. I was considering shadowing the endpoint's original wMaxPacketSize in the substream struct, and replacing the value in the endpoint's native descriptor while the stream is running. I have no idea how much trouble that would cause (eg, corruption elsewhere, or middle finger from Linus). Suggestions? For now I have things working by disabling UHCI's initial bandwidth checks (as there is in fact more than enough bandwidth to schedule what I'm doing) but I'd like a more permanent solution. Monty
