[alsa-devel] [PATCH] Add mute support to FM-only card with FM801 PCI to tuner bridge
by Andy Shevchenko 24 Jan '08

24 Jan '08

Hi! This is improvement of the early support of the FM-only cards where the fm801 chip represents the PCI to tuner bridge. The tuner initialization isn't included the mute on as well as mute support via V4L request. Proposed patch should fix this at least for 64-PCR model.

[alsa-devel] Problems with ALC882
by Christophe Osuna 24 Jan '08

24 Jan '08

Hi, I am having a bad time trying to get an ALC882 [1] to work. I hope that you can help me. Currently I am using alsa-driver-1.0.14 but it would probably be the same with 1.0.15 since there has been no change in /pci/hda/. The ALC882 has got three ADC, and for every one of them it is possible to select one input source. amixer shows my current settings: ~# amixer get 'Input Source',0 Simple mixer control 'Input Source',0 Capabilities: enum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'Mic' ~# amixer get 'Input Source',1 Simple mixer control 'Input Source',1 Capabilities: enum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'Front Mic' ~# amixer get 'Input Source',2 Simple mixer control 'Input Source',2 Capabilities: enum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'Line' Put more simply: Mic -> Input 0 (1st ADC) Front Mic -> Input 1 (2nd ADC) Line In -> Input 2 (3rd ADC) A grep in the proc filesystem shows that there are three ADC and one digital input. ~# cat /proc/asound/card0/codec\#2 | grep Input Node 0x07 [Audio Input] wcaps 0x10011b: Stereo Amp-In Node 0x08 [Audio Input] wcaps 0x10011b: Stereo Amp-In Node 0x09 [Audio Input] wcaps 0x10011b: Stereo Amp-In Node 0x0a [Audio Input] wcaps 0x100391: Stereo Digital So far, so good. But then I try to use the PCM system and things start to go worse. ~# cat /proc/asound/pcm 00-02: ALC882 Analog : ALC882 Analog : capture 2 00-01: ALC882 Digital : ALC882 Digital : playback 1 : capture 1 00-00: ALC882 Analog : ALC882 Analog : playback 1 : capture 2 If my ALSA understanding is right, that means I have two analog input devices (hw:0,0 and hw:0,2). One is missing! If I ask arecord to list the capture devices, it shows the following: ~# ./arecord -l **** List of CAPTURE Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC882 Analog [ALC882 Analog] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 0: Intel [HDA Intel], device 1: ALC882 Digital [ALC882 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 2: ALC882 Analog [ALC882 Analog] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 I have tried to pipe arecord into aplay several times: 1) arecord -f dat -D hw:0,0,0 | aplay -f dat -D hw:0,0,0 2) arecord -f dat -D hw:0,0,1 | aplay -f dat -D hw:0,0,0 3) arecord -f dat -D hw:0,1,0 | aplay -f dat -D hw:0,0,0 (fails) 4) arecord -f dat -D hw:0,2,0 | aplay -f dat -D hw:0,0,0 5) arecord -f dat -D hw:0,2,1 | aplay -f dat -D hw:0,0,0 6) arecord -f dat -D hw:0,0,0 > /dev/null (fails) and arecord -f dat -D hw:0,2,0 > /dev/null (fails) and it shows that: 1) hw:0,0,0 maps to 1st ADC: OK 2) hw:0,0,1 maps to 2nd ADC: OK 3) fails probably because digital input is not activated 4) hw:0,2,0 maps to 1st ADC (same as hw:0,0,0) 5) hw:0,2,1 maps to 2nd ADC (same as hw:0,0,1) 6) when I start the second arecord the first stops (I/O error) and then the second one stops (error), probably because they are working on the same ADC. So it appears that while the "control" ALSA layer detects the 3 ADC the "PCM" layer does not. Do you have any idea of what could be wrong? Besides that I have another smaller problem. According to the ALC882 documentation, the codec can handle 8 kHz signals (by sending setting only one packet on every six packets of the HDA bus which operates at 48 kHz). However the driver will not let me use that sample rate. Example from /proc: Node 0x07 [Audio Input] wcaps 0x10011b: Stereo Amp-In Amp-In caps: ofs=0x08, nsteps=0x1f, stepsize=0x05, mute=1 Amp-In vals: [0x14 0x14] PCM: rates [0x160]: 44100 48000 96000 bits [0x6]: 16 20 formats [0x1]: PCM Connection: 1 0x24 Is this a limit of the HDA implementation? Thanks for your help. [1] http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&Level…

[alsa-devel] Fixing my sound driver
by Adrian McMenamin 24 Jan '08

24 Jan '08

I am still trying to find out what is wrong with my sound driver - for the Sega Dreamcast (sound/sh/aica.c). This works perfectly with the OSS emulation layer but will not work with the ALSA layer per se. As this shows - there is something wrong with how it interacts with the PCM layer of alsa-lib: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: AICA [AICA], device 0: AICA PCM [AICA PCM] Subdevices: 1/1 Subdevice #0: subdevice #0 $ $ $ aplay -L null Discard all samples (playback) or generate zero samples (capture) I have no reason to think that my build of alsa-lib is wrong - both the automagic buildroot build and my own by-hand build behave the same way. So therefore I assume it must be something in the driver?! Some questions: The driver implements nothing for capture (the AICA device is pure playback) - could that have an effect? What information must the driver pass to the PCM layer? What could make the alsa-lib layer detect the card but then report "null" is the only PCM device? Adrian

[alsa-devel] Specific question about ICE1724 + AK4114
by Pavel Hofman 24 Jan '08

24 Jan '08

Hello, I would like to add support for automatic detection of incoming SPDIF sample rate for ICE cards with AK4114 DIR, specifically ESI Juli and Prodigy192 with MI/IODI/O card. Juli windows drivers support the detection, Prodigy drivers don't (broken in some other way too), but the hardware is basically identical. AK4114 support detection by comparing the recovered clock from SPDIF with another clock of 11, 12 or 24MHz, supplied by a crystal, or externally. In both cards this functionality seems to be provided by Xilinx XC9536 CPLD, together with PLL frequency multiplier MK73-1. It all fits together, the CPLD provides the freqency division for PLL feedback of the multiplier. External reference clock input of AK4114 is connected to CPLD, as well as setup pins XTL0/1. Output frequency of MK73-1 specified in datasheet is in the range of 10-50MHz Here is my question: For the PLL multiplier to work, its datasheet says it must be fed with input pulses of 20-50kHz. This frequency could be easily provided by ICE1724, BUT in master mode only. When in slave mode (which is the case for active SPDIF input - clock provided by AK4114), all the clocks are derived from the external clock. This signal obviously cannot be used as reference for the sample rate detection in AK4114 - i.e. basically of itself. According to the ICE1724 datasheet, only I2C and MIDI clocks are derived from the 48kHz mode crystal in slave mode. The datasheed says I2C clock is output only during I2C read/write activity, MIDI clock is not directly output at all. The cards have no other visible crystals/clock modules apart of those two connected directly to ICE1724. I could not trace any connections from the actual crystals to CPLD. Now here I am, absolutely wondering where the CPLD gets its low frequency stable signal for the PLL multiplier, to provide reference clock for SPDIF rate detection. I am afraid without this knowledge I cannot make the detection work in the alsa driver. Hopefully someone experienced in this area will throw a ray of light upon this mystery. Thanks in advance for any ideas, information, suggestions. Best regards, Pavel Hofman.
