[alsa-devel] latency issues
by paul blakeley 21 Nov '07

21 Nov '07

I am currently trying to measure the latency through my alsa application. I will briefly explain my application and set-up. The application has a test harness which sends audio data to my application. To measure the latency the test harness reads in a .wav file(one which I have generated. This contains a short pulse of a sine wave. The rest being zero data.) and also drives the serial port at the point were it detects the sine pulse. As previously explained the audio data is passed through my application and the alsa driver. The difference then between the start of the sine pulse and the output from the sound card is the latency through the system. I measure this with an oscilloscope. Also just to note the test harness is driven from the same sound card as the application, so there should be no difference clocks. Now that I have explained the test scenario, I will explain the behaviour that I am experiencing. To start off, starting the test harness at different instances revealed that the latency measurement is different by maybe 20ms or so, although the alsa buffer levels indicate all is correct. Once started the behaviour is such that the difference drifts ever so slightly. After around 10 minutes the output flips to the beginning and the process starts again. This happens continuously. Without establishing the cause of this problem will ultimately mean the measurement is useless. Could this issue be related to the serial port, alsa buffering, kernel scheduling etc. Can somebody with the relevant experience help. Please.

[alsa-devel] Broken playback
by Gabriele Melia 21 Nov '07

21 Nov '07

Hi All, i'm new so sorry in advance if i do any errors. I have integrated my hw decoder inside ffmpeg that is working fine, but while playing through alsa the sound comes broken in the sense that it is playing for 3 seconds, stops for 1 plays again for 3 sec and stop again and so on. How I can delay the palyback in order to accumulate some decoded buffers to prevent this and to not afflict the decoder when playback is stopping? Thanks, Gabriele _________________________________________________________________ Scarica GRATIS le emoticon della tua squadra del cuore e il calendario di serie A! http://www.emoticons-livemessenger.com/pages/msnitcalcio/index.htm

[alsa-devel] multi pcm and mmap problem
by terminator356＠users.sourceforge.net 21 Nov '07

21 Nov '07

After 2 years I've finally traced and fixed a problem which was preventing me from using anything after ALSA 1.0.9b ! In ALSA lib 1.0.9b: pcm/pcm_generic.c: int snd_pcm_generic_channel_info() { snd_pcm_generic_t *generic = pcm->private_data; return snd_pcm_channel_info(generic->slave, info); } But in ALSA lib 1.0.15: pcm/pcm_generic.c: int snd_pcm_generic_channel_info() { snd_pcm_generic_t *generic = pcm->private_data; if (pcm->mmap_shadow) { /* No own buffer is required - the plugin won't change * the data on the buffer, or do safely on-the-place * conversion */ return snd_pcm_channel_info(generic->slave, info); } else { // Tim: TESTED: This is now called instead of the other one! /* Allocate own buffer */ return snd_pcm_channel_info_shm(pcm, info, -1); } } My multi PCM consists of a plughw:0,2 and a hw:1,0 In ALSA 1.0.9b, all five PCMs ALSA creates for this arrangement create their areas with mmap(). And it works. But in ALSA 1.0.15 my hw:1,0 and its multi PCM areas are created with mmap(), and my plughw:0,2 and its PCMs areas are created with malloc(). Can't hear/record any sound from the plughw:0,2 part of the multi. I have verified that ALSA 1.0.15 is copying the plughw:0,2 HW PCM areas to its LINEAR PCM areas, but NOT finally to its multi PCM areas. It just copies all zeros. That's the reason I hear/record no sound from the plughw:0,2 part of the multi PCM. So I reverted the function's code back to 1.0.9b and presto! It works now, the same as in ALSA 1.0.9b So please tell me, am I missing something? Should I add something more to my .asoundrc ? I see that besides {type multi ... }, there is a {type share ...} defined. *** Does the 'share' have any use here? Can't find any docs on it. Also: Yes, I can see now, why you made this code change. mmap() has limits, so you switched over to malloc(). Those limits force the user to use small buffers and/or reduce the number of channels created. Otherwise aplay, arecord, and jack etc complain mmap() failed. In ALSA 1.0.9b, and after my change to ALSA 1.0.15, I tried ulimit() -l, and editing /etc/security/limits.conf I quadrupled the available locked memory, but aplay, arecord etc still won't let me increase the buffer size beyond what it was BEFORE I edited limits.conf *** What am I doing wrong? Thanks Tim.

[alsa-devel] alsa timestamps
by Heikki Lindholm 21 Nov '07

21 Nov '07

Hello list, I took up some old dusty code of mine that uses snd_pcm_state followed by snd_pcm_status_get_tstamp when in capture mode. The code used to work, but now the returned timestamps are all zeroes. Is there some API change done recently or is the whole timestamping deprecated or something? I've tried with different drivers on ubuntu's alsa .14 and gentoo's .14. I've also tried mmap'ed and r/w modes, and I'm setting the TSTAMP_MMAP sw param. -- Heikki Lindholm

We may use system timers to increase (fine-tune) "interrupt" latencies for pcm streams - see tick time in driver and library.

[alsa-devel] hda-intel codec realtec ALC883
by Jochen Maes 20 Nov '07

20 Nov '07

hey all, just writing because in order to setup my alsa card i had to do some extra steps that might be documented better. steps taken: 1) add to /etc/modules.d/alsa: options snd-hda-intel model=acer-aspire (this is documented) 2) launch alsamixer, go to the capture screen, select the "capture" and press spacebar + set to 75, d the same for "capture 1" the capture simply didn't work otherwise. kind regards, SeJo -- "Defer no time, delays have dangerous ends" "Ne humanus crede" Jochen Maes http://sejo.be http://monitron.org http://www.freenode.net Codec: Realtek ALC883 Address: 0

[alsa-devel] [PATCH 0/3] PNP cleanups - Version 2
by Thomas Renninger 20 Nov '07

20 Nov '07

Changes: - Introduce pnp_irq_no instead of pnp_irq_start (same for dma). - Let irq and dma resource structs never access .end. .end was always only a copy of .start for dma and irq Some background what I want to do next to allocate resources on the fly: I want to use pnp_{port,dma,irq,mem} macros mainly in loops to check whether a resource got allocated: e.g.: - if (idx >= PNP_MAX_DMA) { + if (!pnp_dma(dev, idx)) { or: - for (idx = 0; idx < PNP_MAX_IRQ; idx++) { + for (idx = 0; pnp_irq(dev, idx); idx++) { that would look like this in pnp.h: +#define pnp_port(dev,bar) ((dev)->res.allocated_ports > (bar) \ + ? (&(dev)->res.port_resource[(bar)]) : NULL) I'd like to use krealloc to realloc portions of e.g. 8 port resources on the fly. As krealloc modifies the addresses of the array, it must be insured that these are only used at pnp parse time. This seem to work fine for pnpacpi, were most of the: echo {get,fill,clean,...} >/sys/devices/pnp0/*/resources interface does not work for me :) It should be possible to get this working, if I could get some testing help with these interfaces, that would be great. Is any tool making use of this? The "get" looks evil. It reparses the devices' BIOS information. This should work as long as not more resources are attached to a device compared to the initial parse and krealloc must pop in, this should be the case... I wonder whether this get and possibly other sysfs interfaces in drivers/pnp/interface.c can be reverted (it's debug only?). Then the whole parsing code could theoretically be made __init data. Bjorn? Also the pnp_resource_change exported symbol could be a problem, if resources are simply defined by the driver, even there were none (allocated) found by the pnp{isa,bios,acpi} parser. But this should be "workaroundable" by doing one malloc/krealloc portion there. It must be called before insert_resource(..) got called anyway (which passes the address of a struct resource to be registered as global used IO/System Memory). Invalidating the passed struct resource pointers afterwards would be fatal. Just found that problem, I haven't looked at it in detail. Any help, comments, etc. are very much appreciated, Thomas

[alsa-devel] Duplex syncronization in ALSA
by Fredrik Lingvall 20 Nov '07

20 Nov '07

Hi all, I am an researcher in the field of acoustic (ultrasonic) signal processing. Normally we use dedicated hardware where the transmit and receive processes are synchronized. Now I want to use a multi-channel sound card (in my case a RME Multiface card) to perform, for example, simple beamforming. Typically, one transmit pulses on an array of transducers (speakers) where each pulse is delayed a certain amount to create focusing or beemsteering. By knowing the soundspeed in the propagation medium one can calculate the double path time-of-flight to various points and then, by beamforming the received signals, one can get an image of the objects that are in front of the acoustic array. Now to my problem: in order to do the processing one need to know the delay in the system from transmit to receive. I have looked at the ALSA lib API docs and some code examples (pcm.c, aplay etc) and it looks like the playback and capture processes are independent in ALSA (i.e., there is no write-and-read-at-the-same-time function). The latency inherent in the soundcard isn't that much of a problem if it is know. It is, however a problem if the latency from transmit to receive is not constant from measurement to measurement. I have written some code (for Octave) that uses MMAP and poll:ing but I don't see how to synchronize the write and read processes (they use two different poll fd:s). What is the best way to do this? Is it possible at all? Regards /Fredrik

[alsa-devel] snd_pcm_status_get_avail() values
by Markus Korber 20 Nov '07

Hello, I've got a driver with the following settings: ,---- | static const struct snd_pcm_hardware svenm_pcm_hardware = { | .info = SNDRV_PCM_INFO_MMAP | | SNDRV_PCM_INFO_MMAP_VALID | | SNDRV_PCM_INFO_BLOCK_TRANSFER | | SNDRV_PCM_INFO_PAUSE | | SNDRV_PCM_INFO_RESUME | | SNDRV_PCM_INFO_INTERLEAVED, | .formats = SNDRV_PCM_FMTBIT_S16_LE | | SNDRV_PCM_FMTBIT_U16_LE, | .channels_min = 2, /* 2 = only stereo */ | .channels_max = 2, | .period_bytes_min = 8*1024, | .period_bytes_max = 8*1024, | .periods_min = 2, | .periods_max = 2, | .buffer_bytes_max = 4*8*1024, | }; `---- ,----[ _pcm_prepare() ] | chip->playback.hw_buffer_size = prtd->period_bytes * 2; /* byte size */ | chip->playback.sw_buffer_size = snd_pcm_lib_buffer_bytes(substream); `---- Since my HW only allows for a period number of 2, I would like to always receive period_bytes_min(max) input bytes from an application (mplayer, xine, etc.) so that I can always fill one complete HW output buffer. The application (mplayer) does [3] to determine the number of bytes it is allowed to write with snd_pcm_writei() (for logging see [4]): ,----[ 3 ] | bytes_to_write = snd_pcm_status_get_avail(status) * bytes_per_sample; `---- (Here 1 sample equals 4 bytes, S16_LE, stereo.) ,----[ 4 ] | fill_audio_out_buffers: bytes_to_write=16384 | alsa-play: frames=4096, len=16384 | fill_audio_out_buffers: bytes_to_write=8192 | alsa-play: frames=2048, len=8192 | fill_audio_out_buffers: bytes_to_write=8192 | alsa-play: frames=2048, len=8192 | fill_audio_out_buffers: bytes_to_write=8192 | alsa-play: frames=2048, len=8192 | fill_audio_out_buffers: bytes_to_write=16384 | alsa-play: frames=4096, len=16384 | fill_audio_out_buffers: bytes_to_write=16384 | alsa-play: frames=4096, len=16384 `---- Furthermore, I'm using the pcm-indirect framework[1] and my hw_ptr always toggles between 0 and period_bytes[2] (bufnum refers to the HW playback buffer number). ,----[ 1 ] | static snd_pcm_uframes_t | chip_pcm_pointer(struct snd_pcm_substream *substream) | { | ... | return snd_pcm_indirect_playback_pointer(substream, &chip->playback, | prtd->playback_hw_ptr); | } `---- ,----[ 2 ] | if (bufnum == 0) | prtd->playback_hw_ptr = 0; | else | prtd->playback_hw_ptr = prtd->period_bytes; `---- Thus, how is the value returned by snd_pcm_status_get_avail determined? I mean, if my pointer always toggles between 0 and period_bytes[2], how can ALSA return the values logged in [4]? Would this mean that I'm not able to process (in the application) the samples fast enough and the HW buffer runs empty in the meantime? (I would expect snd_pcm_status_get_avail to always returns 8192.) Or is there an additional parameter or constraint to somehow limit the input sample number from an application? Thanks.
