[alsa-devel] [PATCH]alsa:patch_realtek.c iMac9,1 sound fixes.
by Justin P. Mattock 25 May '10

25 May '10

What seemed to be a simple little task of getting the microphone to work, ended up becoming a bigger task than I had set out. (oh-well, good learning experience). Anyways below you will find an updated patch to the iMac9,1 machine which fixes some issues that I found.(keep in mind this is still a work in progress). First issue: With the original patch, I've noticed by unmuting the mic (and even having it muted), there is a distorted("Noise") coming from the internal speakers, even when the headphones are plugged in. What my finding's revealed is: /* Mic (rear) pin: input vref at 80% */ {0x18, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_VREF80}, {0x18, AC_VERB_SET_AMP_GAIN_MUTE, AMP_OUT_MUTE}, _From the original patch. Looking at codec#0 0x18/0x1a is listed as: Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x00 0x00] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x90100141: [Fixed] Speaker at Int N/A Conn = Unknown, Color = Unknown DefAssociation = 0x4, Sequence = 0x1 Misc = NO_PRESENCE Pin-ctls: 0x41: OUT VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c* 0x0d 0x0e 0x0f 0x26 seems this Node is listed as: [Fixed] Speaker while 0x15 Node 0x15 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0 Amp-In vals: [0x00 0x00] Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x80 0x80] Pincap 0x0000373c: IN OUT HP Detect Vref caps: HIZ 50 GRD 80 100 Pin Default 0x018b3020: [Jack] Line In at Ext Rear Conn = Comb, Color = Blue DefAssociation = 0x2, Sequence = 0x0 Pin-ctls: 0x01: VREF_50 Unsolicited: tag=00, enabled=0 Connection: 5 0x0c 0x0d* 0x0e 0x0f 0x26 is [Jack] Line In at Ext Rear. (looking at the other apple products as examples I came up with the fix below). Second issue: alc885_mbp_4ch_modes The original patch does a good job with the HP pin automute function, but from what I noticed is I would have to manually change the channel form 2 to 4 after plugging the headphones in. And not to mention having odd moments to where I was jamming out with the headphones on, then later realized I had sound blasting out of the speakers as well. My findings revealed that changing alc885_mbp_4ch_modes to alc885_mba21_ch_modes and setting - spec->autocfg.speaker_pins[0] = 0x15; + spec->autocfg.speaker_pins[0] = 0x18; gets the automute function when the headphones plugged in working flawlessly(and the no need to manually change the channel number afterwards). Third issue: alc885_imac91_mixer There probably doesnt need to be anything changed with this (esspecially if your one to like lots of sliders),but my findings revealed that mac osx only has a master on the top right, another switch on itunes, and then a slider for the mic. So the changes I did below try and mimic osx as much as possible (only thing I had an issue with is just having one mute switch on the master, instead of having two(still investigating)). fourth issue: alc882_capture_source I endeded up creating alc889A_imac91_capture_source() only because looking at alc882_capture_source I see that the mic is set to 0x1 while this works, I also noticed that adding 0x1 and 0x01 and testing that 0x1 somehow stops working, and 0x01 works(so I figured 0x01 was more of the alpha of the numbers(still need to figure out where that valuse is)). In any case the microphone does work with the original, and with the below patch, but both still record not as clean(lots of "Noise", which I would like to look into too). Note: using alsamixer -Va reveals the capture switches. Overall the original patch is good, the below patch does (hopefully)address some issues, if it's too much of a change I can go back, and just adjust the verb pins on the original and just call it that..(main thing over here is I don't have the "Noise" coming out of the speakers(and music sounds good)... cheers..

ok you can find attached my codec0 output data. I hope this helps. if you or anyone else need any other piece of info, please ask. ---- Messaggio originale---- Apparently (I assume) this is not for all via sound chips so it's best to expalin what your setup is. The output from lspci does not tell the story on the codec at times.

[alsa-devel] Type safe Haskell interface to ALSA sequencer
by Henning Thielemann 25 May '10

25 May '10

Dear ALSA developers, I read the ALSA-Sequencer-API-Doxygen documentation, various ALSA-MIDI-How-Tos and their examples and succeeded to work with ALSA sequencers in Haskell. However, I'm still uncertain about the meaning of the system components and how they interact. It is extensively documented, what works, but not, what does not work. Whenever I do a mistake, ALSA leaves me with an unspecific "operation not permitted" or "invalid argument" error code. Thus I try to encode conditions in Haskell types. For instance once I got an "Invalid argument" error code and only after some investigation, I found that I opened the sequencer in Output mode but later called event_input. (Actually I only wanted to output something, but used event_input for synchronization using Echo events. Unfortunately the intention of Echo messages is even not explained in the Doxygen stuff.) In order to prevent another occurrence of this problem, I defined distinct Haskell types for sequencers depending on the input mode. Now, event_input is only allowed on sequencers that were opened in Output or Duplex mode. However I wondered, why I could create writeable ports in a output-only sequencer. Does this make sense? Would it be reasonable to forbid writeable ports in output sequencers and readable ports in input sequencers by Haskell types? Is there a difference between cap_read|cap_write and cap_duplex? I also wondered why there can be several ports in one sequencer, since multiple clients can connect to one port, and event_input and event_output have no port argument. Further I wondered why queues are not bound to a specific port. Can queues be shared amongst ports? Is it sensible to have multiple queues in one sequencer? Why has sync_output_queue no queue argument? The more I think about it, it seems to me that a port is more an identifier, a part of an address, than a mailbox. I could use ports as tags, that tell which part of an application to control. A queue looks like a mail company and I can use the same sender and receiver addresses across different companies. If this is true, then I think it would be worth to mention this in the API documentation. In another example I called sync_output_queue in order to wait for all events being sent, but it aborted with "Operation not permitted", whereas I have seen example code where it works. What are the preconditions to calling sync_output_queue? I really like to see a picture of how sequencers, clients, ports, port_infos, queues, timers, events are related.

[alsa-devel] [PATCH 1/1] ALSA: usb-audio: add support for Akai MPD16
by Krzysztof Foltman 25 May '10

25 May '10

The decoding/encoding is based on own reverse-engineering. Both control and data ports are handled. Writing to control port supports SysEx events only, as this is the only type of messages that MPD16 recognizes.

[alsa-devel] MMAP in ALSA
by Varadarajan, Srikanth 25 May '10

25 May '10

Hi All, I am new to the list and ALSA. For the hardware I am working with, we expose it to ALSA as one card capable of playing one PCM stream. If we have one application using the hardware through ALSA, other applications are unable to get access to it. So, we want to have PulseAudio on top and use the pulse virtual device to render audio through ALSA. Is this a recommended way of having multiple applications access one audio HW simultaneously? Is there any other way of handling multiple applications get access to the same hardware? Also, why are mmap and munmap operations required in ALSA? Right now, we do not have mmap and munmap operations exposed. Though the hardware constraints have "SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_MMAP_VALID" defined. Looks like, if we have to PulseAudio on top, mmap operations are required in ALSA. If there is a close enough ALSA implementation in the current Linux kernel that I can lookup, please point me to that. Any help/suggestions are welcome. Thanks, Srikanth
