[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

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.

[alsa-devel] Strange bug in .asoundrc ??
by Dominique Larchey-Wendling 19 Nov '07

19 Nov '07

Dear all, It seems that neither the current ctl.hw function nor the following simplified function ctl.!hw work correctly when the argument CARD is given to the function. It works however when no argument is given as the following test examples show it. It have alsa-lib version 1.0.14-0.4.rc3.fc7 installed on FC7. Is this a know bug of alsa-lib ? It is strange because this bug does not show up with pcm.hw for example. --- .asoundrc ------------------------ ctl.!hw { @args [ CARD ] @args.CARD { type string default "0" } type hw card $CARD } ctl.rha "hw" ctl.tata "hw:0" ctl.toto "hw:1" ------------------------------------------------ rha % amixer -D rha info Card rha 'Intel'/'HDA Intel at 0xfebfc000 irq 16' Mixer name : 'SigmaTel STAC9200' Components : 'HDA:83847690' Controls : 6 Simple ctrls : 4 rha % amixer -D tata info ALSA lib control.c:781:(snd_ctl_open_conf) Invalid type for CTL tata definition amixer: Control device tata open error: Invalid argument rha % amixer -D toto info ALSA lib control.c:781:(snd_ctl_open_conf) Invalid type for CTL toto definition amixer: Control device toto open error: Invalid argument

[alsa-devel] No sound on Intel DQ965GF motherboard
by Eric S. Raymond 19 Nov '07

19 Nov '07

Thank you, alsa developers, for the prompt resolution of my previous sound issue with the Thinkpad X61. Unfortunately, I've now turned up an apparently different problem on very similar hardware. Sound doesn't work on my DQ965GF motherboard under Ubuntu 7.10. Here's what I've found out about it. I'm writing in hope that someone on the ALSA devel list can suggest diagnostics to pin down the problem exactly. The device has PCI ID [8086:284b] (rev 02). It is an Intel 82801H. This appears to be an Ubuntu-specific error. At http://www.linuxquestions.org/questions/linux-hardware-18/intel-dq965gf-mob… I found a post implying that at least the rear jacks on the mobo are active under Fedora Core 6. I have therefore filed an Ubuntu bug at https://bugs.launchpad.net/ubuntu/+bug/162410 but seen no response. This also appears to be a very hardware-configuration-specific error. I have an Intel HDA audio device on my X61 laptop with PCI ID [8086:284b] (rev 03), another 82801H, that works just fine under Ubuntu 7.10 (the alsa version is nominally 1.0.14 but some 1.10.15 fixes, including the right one, were backported). Note the 03 as opposed to 02 subrev. aplay -l, which is supposed to list sound playback devices, returns no listing on the DQ965GF. As a check, on the X61 where it works it returns this: card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 lsmod also returns suggestively different results. On the laptop, its output includes this line. snd_hda_intel 337192 1 On the DQ965GF, here are the sound device lines: snd_hda_intel 337192 0 snd_usb_audio 96640 1 snd_pcm_oss 50048 0 snd_mixer_oss 20096 1 snd_pcm_oss snd_pcm 94344 3 snd_hda_intel,snd_usb_audio,snd_pcm_oss snd_usb_lib 20352 1 snd_usb_audio snd_seq_dummy 5380 0 snd_seq_oss 36864 0 snd_seq_midi 11008 0 snd_seq_midi_event 9984 2 snd_seq_oss,snd_seq_midi snd_seq 62496 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 27272 2 snd_pcm,snd_seq snd_rawmidi 29824 2 snd_usb_lib,snd_seq_midi snd_seq_device 10260 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq,snd_rawmidi snd_hwdep 12168 1 snd_usb_audio snd 69288 13 snd_hda_intel,snd_usb_audio,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_rawmidi,snd_seq_device,snd_hwdep soundcore 10272 1 snd snd_page_alloc 12560 2 snd_hda_intel,snd_pcm usbcore 161584 8 usbhid,snd_usb_audio,snd_usb_lib,xpad,gspca,ehci_hcd,uhci_hcd Note that snd_hda_intel has no users and that snd_usb_audio has 1. On the DQ965GF, the Sound Preferences tab on my Gnome toolbar thinks the sound device is "USB Device 0x46d:0x8ad (ALsa mixer)". I don't know what tool GNOME is running to determine this. This arch-linux thread gave me some insight: http://bugs.archlinux.org/task/6617 It appears the snd_usb_audio driver is a red herring, or at least a separate bug. I checked, and my dmesg log does indeed say "hda-intel: no codecs found!" on boot, which suggests that snd_hda_intel is loading and then failing to initialize properly, accounting for the usage count of 0. I tried reverting the kernel patch mentioned in the arch thread (e.g. recompiling the snd_hda_intel driver with #define AZX_MAX_CODECS 4) but this did *not* solve the problem. Any suggestions would be appreciated. I need my music back! -- <a href="http://www.catb.org/~esr/">Eric S.
