[alsa-devel] [PATCH] New Aztech Sound Galaxy driver
by Rene Herman 25 Sep '07

25 Sep '07

Hi Takashi. This is a new driver for Aztech Sound Galaxy ISA soundcards based on the AZT1605 and AZT2316 chipsets. It's constructed as two seperate drivers for either chipset generated from the same source file, with (very) minimal ifdeffery. The drivers check the SB DSP version to decide if they are being loaded for the right chip. AZT1605 returns 2.1 by default, and AZT2316 3.1. This isn't full-proof as the DSP version can actually be set through software but it's close enough -- as far as I've been able to see, the DSP version can not be stored in the EEPROM and the cards will therefore startup with the defaults. This distinction could (with the same success rate) also be used to decide which chip we're looking at at runtime meaning a single, merged driver is also an option but I feel it's actually nicer this way. A merged driver would have to postpone translating the passed in resource values to the card configuration until it knew which one it was looking at and would need to postpone erring out on mpu_irq=10 for azt1605 and mpu_irq=3 for azt2316. If you differ, I will merge them, but I'd rather keep them seperate. The drivers have been tested on various cards. For snd-azt1605: FCC-ID I38-MMSN811: Aztech Sound Galaxy Nova 16 Extra FCC-ID I38-MMSN822: Aztech Sound Galaxy Pro 16 II and for snd-azt2316: FCC-ID I38-MMSN824: Aztech Sound Galaxy Pro 16 AB FCC-ID I38-MMSN826: Trust Sound Expert DeLuxe Wave 32 (05201) FCC-ID I38-MMSN830: Trust Sound Expert DeLuxe 16+ (05202) FCC-ID I38-MMSN847: Trust Sound Expert DeLuxe Wave 32-3D (06301) FCC-ID I38-MMSN852: Aztech Sound Galaxy Waverider Pro 32-3D I38-MMSN826 is also known as "Aztech Sound Galaxy Waverider 32+". All cards work fully -- full-duplex PCM, MIDI and FM. Full-duplex is a little flaky on some. I38-MSN811 tends to not work in full duplex, but sometimes does with the highest success rate being achieved when you first start the capture and then a playback instead of the other way around (it's a CS4231-KL codec). The cards with an AD1845XP codec (my I38-MMSN826 and one of my I38-MMSN830s) are also somewhat duplex-challenged. Sometimes full-duplex works, sometimes not and this varies from try to try. This seems likely to be a timing problem somewhere inside cs4231-lib. I38-MMSN826 has an additional "ICS2115 WaveFront" wavetable synth onboard that isn't supported yet. The wavetable synths on I38-MMSN847 and I38-MMSN852 are wired directly to the standard MPU-401 UART and the AUX1 input on the codec and work without problem. CD-ROM audio on the cards is routed to the codec "Line" input, Line-In to its Aux input, and FM/Wavetable to its AUX1 input. I did not rename the controls due to the capture source enumeration: I see that capture-source overrides are hardcoded in cs4231-lib and this is just too ugly to live. Versus the old snd-sgalaxy driver, these drivers add support for the models without a configuration EEPROM (common), full-duplex, MPU-401 UART and OPL3. In the future they should grow support for that ICS2115 WaveFront synth on 826 and an hwdep interface to write to the EEPROM on the models that have one. lib.c was split off in preparation of having snd-azt2320 use it as well and generally containing non soundgalaxy specific code that might at some point make it into an isa/lib.c or something. It's tiny, so it's not constructed as a helper module but simply compiled into both drivers. Signed-off-by: Rene Herman <rene.herman(a)gmail.com> [ all of the above is intended as a changelog ] Given that they are new drivers with new names, they shouldn't disturb anything and can as far as I'm concerned make 1.0.15 but if you feel it's too late (and/or don't want the two seperate drivers), so be it. I can also submit a next patch removing the old sgalaxy driver now or just wait with that one... Patch is against current alsa-kernel hg.

[alsa-devel] race conditions in alsa core
by Trent Piepho 24 Sep '07

24 Sep '07

In the process of trying to discover that kind of locking ALSA provides to a driver and what the driver must take care of itself, I think I have found some race conditions inside the alsa core. I think there are likely quite a few, but this example was one of the easiest to prove. ALSA uses unlocked_ioctl, which means ioctl calls aren't protected by the BKL and may run at the same time. Some ioctls, for instance HW_PARAMS, don't appear to have any locking done by ALSA. It's entirely possible for two hw_params calls to run at the same time on the same substream, and the ALSA core (and probably many drivers too) can't handle this. The following patch helps to create a larger window for the race condition, so that it can be triggered consistently. --- a/sound/core/pcm_native.c Tue Sep 04 09:02:06 2007 +0000 +++ b/sound/core/pcm_native.c Sat Sep 22 17:12:37 2007 -0700 @@ -411,6 +411,7 @@ static int snd_pcm_hw_params(struct snd_ runtime->channels = params_channels(params); runtime->rate = params_rate(params); runtime->period_size = params_period_size(params); + { static unsigned long x=1; if(test_and_change_bit(0, &x)) msleep(10); } runtime->periods = params_periods(params); runtime->buffer_size = params_buffer_size(params); runtime->tick_time = params_tick_time(params); This causes every other call to snd_pcm_hw_params() to have a 10ms delay between setting the period size and period count. If there are two calls within 10ms, the period count should come from the first call (which slept), while the period size will be from the second call. My test program will call the HW_PARAMS ioctl twice from different threads running at the same time. The first call will ask for the maximum number of periods with minimum size, the second call for the minimum number of periods of maximum size. When prepare is called, we discover that the runtime is set for the maximum number of periods of maximum size, which exceeds the buffer size. Of course even if it didn't exceed the buffer size, the params should be from one call or the other, not some random combination of both. I've attaching a very simple dummy ALSA driver which shows this. All it does is print timestamps and a few parameters when the various callback functions are invoked. The output looks like this: as_open - 0.084 us as_hw_params - 552.864 us periods 128, period size 1024 as_hw_params - 589.996 us periods 1, period size 131072 as_prepare - 11065.307 us periods 128, period size 131072 as_close - 11278.229 us Notice how in prepare the runtime has parameters that are a combination of the two hw_params calls. This test program should trigger the same race with any other ALSA driver. Just adjust the period count and size. The test program doesn't use the ALSA lib. It does need the headers from the alsa lib package to compile, since this seems to be the only place where user space headers for the device interface are provided.

[alsa-devel] Emux hwdep ioctl requests
by Claudio Matsuoka 24 Sep '07

24 Sep '07

Hi, I'm writing an application for Emux patch loading using asfxload as reference, and noticed that there are many ioctl request definitions specified in the application instead of in a system header file. Should I do the same redefining SNDRV_EMUX_IOCTL_VERSION, SNDRV_EMUX_IOCTL_LOAD_PATCH, etc. or there are plans to place these in a common location? Also it seems that current Ubuntu doesn't have /usr/include/linux/awe_voice.h, has that been deprecated for some reason or it's just a bug in the distro?

[alsa-devel] OSS sequencer mode and SNDCTL_SEQ_CTRLRATE
by Claudio Matsuoka 24 Sep '07

24 Sep '07

Hi, Using the OSS sequencer mode of ALSA, I noticed that a request for SNDCTL_SEQ_CTRLRATE always returns 100 regardless of the kernel HZ value. I therefore assume that the OSS sequencer mode always works at this rate, unlike real OSS which varies with the kernel HZ, is that correct?

[alsa-devel] Sound trouble with MCP61 chipset.
by Steven Young 23 Sep '07

23 Sep '07

Hi, I had sent a message a couple of weeks ago regarding a somewhat reproducible error I'm having with onboard audio for systems with the MCP61 chipset. Specifically, the left channel doesn't work, and emits a high-pitched tone whenever the audio device is open. Also, adjusting the volume disables all sound until the kernel modules for sound are all reloaded. I didn't receive any response to that message; is this the right place to ask? I have two machines, both with the MCP61 chipset, and both with the same problem. I have included the lspci -v output of one of them below.

[alsa-devel] [PATCH] opti93x: conversion to use cs4231 library
by Krzysztof Helt 22 Sep '07

22 Sep '07

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> This patch converts the Opti93x driver to use the cs4231 library instead of just duplicating the code. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This patch requires the patch which adds opti93x support to the cs4231 library. This patch is just first pass to remove the code not used any more and just hook the driver into the cs4231 library. It can be improved as well as made more coding style correct. It was tested with full-duplex audio on the opti931 card.

[alsa-devel] [PATCH] cs4231-lib: add support for Opti93x codec
by Krzysztof Helt 22 Sep '07

22 Sep '07

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> This patch adds support for WSS compatible Opti93x codec to the cs4231-lib. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This allows to remove cs4231 duplicated code from the opti93x driver. It is almost half of the opti driver. The opti93x must use its own interrupt handler so it needs also the overrange function. That's why it is exported. The next patch will convert the opti93x driver to use the cs4231 library instead of its own code. The cs4231 library (and ad1848's) gets improved with Rene's and Trent's help so this should improve the opti driver as well.

[alsa-devel] Phoenix Audio Duet
by Shane Hathaway 22 Sep '07

22 Sep '07

Hello, I just bought a set of Phoenix Audio Duets for VOIP conferencing. They are USB speakerphones with good echo cancellation. They work fine with the snd_usb_audio module, with one exception: I can't control the microphone and speaker levels. ALSA exposes some controls, but they have no effect, so I have to shout to be heard. Rather than get a hoarse voice, I want to help enhance the snd_usb_audio module to correctly support the mixer controls within the Duet. I know the device actually has working mixer controls because Phoenix Audio provides a Windows-only utility for controlling the levels, and when I use that utility turn up the mic, I can be heard quite well. Unfortunately, the levels are reset when I move the device back to a Linux box. I used SnoopyPro to capture USB packets as I adjusted the levels in Windows and I think I know what to transmit to the device in order to read and change the levels. Now I just need to figure out how to translate that knowledge into kernel code. I am a capable C coder (though rusty), I don't know much about USB, and I've dabbled in kernel code before. lsusb lists the Duet (Executive) as: Bus 001 Device 011: ID 0556:0004 Asahi Kasei Microsystems Co., Ltd Both kmix and Ekiga see it as an AK4571. There is a data sheet for that chip here: http://www.datasheetcatalog.com/asahikaseimicrosystems/3/ I would guess that the AK4571 has mixer controls built in, but that Phoenix Audio (phnxaudio.com) chose not to use those controls and instead enhanced the USB interface with nonstandard mixer controls. So, where should I begin? I don't see evidence that anyone has worked on this yet. Shane
