[alsa-devel] Why is a USB capture device showing up in "aplay -L"?
by Chris Rankin 01 Dec '07

Hi, I have a webcam which has microphone-only USB audio capability. However, not only has this device stopped recording anything but it has also vanished from the "arecord -L" list and appeared in the "aplay -L" one instead: $ arecord -L default:CARD=Audigy2 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Default Audio Device front:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Front speakers rear:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Rear speakers center_lfe:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Center and Subwoofer speakers side:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Side speakers surround40:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 4.0 Surround output to Front and Rear speakers surround41:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback IEC958 (S/PDIF) Digital Audio Output null Discard all samples (playback) or generate zero samples (capture) and: $ aplay -L default:CARD=Audigy2 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Default Audio Device front:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Front speakers rear:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Rear speakers center_lfe:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Center and Subwoofer speakers side:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback Side speakers surround40:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 4.0 Surround output to Front and Rear speakers surround41:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Audigy2,DEV=0 Audigy 2 ZS [SB0353], ADC Capture/Standard PCM Playback IEC958 (S/PDIF) Digital Audio Output null Discard all samples (playback) or generate zero samples (capture) default:CARD=WebCam USB Device 0x46d:0x8b4, USB Audio Default Audio Device front:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio Front speakers surround40:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=WebCam,DEV=0 USB Device 0x46d:0x8b4, USB Audio IEC958 (S/PDIF) Digital Audio Output Here is my .asoundrc file: ctl.Audigy2 { type hw card 0 } pcm.Audigy2 { type plug slave { pcm "hw:0,0" } } ctl.webcam { type hw card 1 } pcm.webcam { type plug slave { pcm "hw:1,0" } } and here is what /proc/asound looks like: ]$ ls -als /proc/asound/ total 0 0 dr-xr-xr-x 6 root root 0 2007-12-01 15:55 . 0 dr-xr-xr-x 172 root root 0 2007-12-01 14:37 .. 0 lrwxrwxrwx 1 root root 5 2007-12-01 15:55 Audigy2 -> card0 0 dr-xr-xr-x 11 root root 0 2007-12-01 15:55 card0 0 dr-xr-xr-x 3 root root 0 2007-12-01 15:55 card1 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 cards 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 devices 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 hwdep 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 modules 0 dr-xr-xr-x 2 root root 0 2007-12-01 15:55 oss 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 pcm 0 dr-xr-xr-x 2 root root 0 2007-12-01 15:55 seq 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 timers 0 -r--r--r-- 1 root root 0 2007-12-01 15:55 version 0 lrwxrwxrwx 1 root root 5 2007-12-01 15:55 WebCam -> card1 This happens with both Fedora 7 and Fedora 8.

Changing e-mail address of list is something I don't want. The official e-mail address for alsa-devel mailing list was always alsa-devel(a)alsa-project.org (even in time when this list was on sourceforge). Unfortunately, vger mailing list does not accept simple redirected e-mails from alsa-devel(a)alsa-project.org so I postponed any actions. > - open alsa-project.org list again. I'll stop list admin works. I tried to count some statistics and at the time spamassassin and mailman filtering rules catch 92% of spam messages coming to alsa-devel. Unfortunately remaining 8% means 20 spam messages daily (without moderation). Could moderators confirm this value?

[alsa-devel] [PATCH] sound/isa: kill pnp_resource_change.
by Rene Herman 30 Nov '07

30 Nov '07

Hi Takashi. This removes the pnp_resource_change use from the ALSA ISAPnP drivers. In 2.4 these were useful in providing an easy path to setting the resources, but in 2.6 they retain function as a layering violation only. This makes for a nice cleanup (-550 lines) of ALSA but moreover, ALSA is the only remaining user of pnp_init_resource_table(), pnp_resource_change() and pnp_manual_config_dev() (and, in fact, of "struct pnp_resource_table") in the tree outide of drivers/pnp itself meaning it makes for more cleanup potential inside the PnP layer. Thomas Renninger acked their removal from that side, you did from the ALSA side (CC list just copied from that thread). Against current alsa-kernel HG. Many more potential cleanups in there, but this _only_ removes the pnp_resource_change code. Compile tested against current alsa-kernel HG and compile- and use-tested against 2.6.23.x (few offsets).

Re: [alsa-devel] Edirol UA-4FX
by David Hubbard 30 Nov '07

30 Nov '07

Hello Luis, and Alsa list, I recently got an Edirol UA-4FX. It works just fine as a generic USB Audio device. I've written up all the details at http://alsa.opensrc.org/index.php/Edirol_UA-4FX (shamelessly stolen from the Edirol_UA-25 page). The the UA-4FX needs a patch to usbaudio.c create_ua700_ua25_quirk() and usbquirks.h, and then it has full support. (MIDI I/O, sample rates up to 96 kHz) I've made an attempt, mostly to get it working on my machine. Can you review it? Thanks, David

[alsa-devel] Export symbols in alsa-lib
by Takashi Iwai 30 Nov '07

30 Nov '07

Hi, during the discussions with LSB guys, it turned out that the current ALSA-lib has many exported symbols that are not actually considered to be public. I fixed these unneeded exports in the HG tree. If you find some problems with this change, please let me know. thanks, Takashi

[alsa-devel] ALSA API as standards
by Takashi Iwai 30 Nov '07

30 Nov '07

Hi, I've talked with some people workiong on LSB about the possibility to put libasound as a part of the next LSB (surprisingly, they would like it more than I). I proposed that we should define the minimal set at first as the standard instead of taking all existing API functions. An interesting input was that they did some statistics and counted the actual used functions/variables in ALSA API over distros. The data is attached below. I just put the number of apps and functions there to simplify. (It includes __* functions that are actaully internal ones, and I'm wondering why their numbers are so high. Anyway, they shouldn't be a part of standard.) So, first, just take a look at it. You'll see how many functions are not actually used at all. What I'd like to do now are: - create a list of "standard" functions to be passed to LSB - clean up and actually drop some non-used functions - remove some functions from export list (in Versions file) I'll try to create a list. Basically it'll be almost as same as the list of functions with count > 0, plus some related ones. Then, let's discuss and clean up... BTW, regarding Versions. The versioned symbols for newly added functions seem not set properly as expected. We have entries ALSA_0.9 { global: __snd_*; _snd_*; snd_*; local: *; }; and thus the rest functions after this all belong to ALSA_0.9 in the end (except for functions explicitly defined with obsolete macros in pcm.c). It means, we'll need to stick with ALSA_0.9 tag no matter which version is added. Only if the function API is changed and double definitions are needed, we'll tag to another version... Oh well.

[alsa-devel] Some drivers don't create all necessary sysfs symlinks
by Lennart Poettering 30 Nov '07

30 Nov '07

Hi! Apparently not all ALSA drivers set the "device" symlink properly. This creates problems with HAL which then is unable to manage permissions to those files properly. One example of such a driver is EMU10K1X. For more information, see: https://bugzilla.redhat.com/show_bug.cgi?id=370821#c26 Also reported on the ALSA BTS: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3575 Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net ICQ# 11060553 http://0pointer.net/lennart/ GnuPG 0x1A015CC4

[alsa-devel] Problems while using mplayer based on ALSA

Hi All: Im having problems while using mplayer 1.0 to play music based on alsa 1.0.15. Im using an ARM9 system and montavista linux 2.6.18.

[alsa-devel] HDA or AC97 for Nvidia MCP61S?
by alsa-devel.20.pris＠spamgourmet.com 30 Nov '07

30 Nov '07

Hello, as I already reported on another email I'm having problems with my sound: http://thread.gmane.org/gmane.linux.alsa.devel/49412 My motherboard is PCCHIPS A13G+. The sound hardware of my Mobo is in the NVIDIA MCP61S Single chipset. This chipset consists of: GeForce(R) 6100 GPU and MCP nForce(R) 405 Codec: Realtek ALC660-VD When looking at the soundcard matrix for Nvidia there are 2 options listed: http://www.alsa-project.org/main/index.php/Matrix:Vendor-Nvidia AC97 nForce-1 - nForce-4 HDA nForce-430 and later Since my chipset is nForce 405 should I select the first option AC97? But everyone seems to advise me to use the HDA option. When I look at the details for HDA I see only "Intel HDA driver" and nothing about which particular chipsets are supported. On the AC97 option there is a list of chips but all are from Intel and none from Nvidia. So I'm confused. Which soundcard is the correct one for me? Is my particular chipset supported at all? Thanks!

[alsa-devel] pcm test app failure on PowerPC
by John Faith 29 Nov '07

29 Nov '07

Hello, I am using alsa-lib 1.0.15 on an embedded PowerPC board. I can play audio with aplay, but gstreamer fails, so I built and ran the 'pcm' app in alsa-lib-1.0.15/test/. pcm gives: # export LIBASOUND_DEBUG=1 # ./pcm Playback device is plughw:0,0 Stream parameters are 44100Hz, S16_BE, 1 channels Sine wave rate is 440.0000Hz Using transfer method: write ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'plughw:0,0' ALSA ERROR hw_params: set (FORMAT) value = S16_BE : Invalid argument ACCESS: RW_INTERLEAVED FORMAT: S8 U8 S16_LE S16_BE U16_LE U16_BE S24_LE S24_BE U24_LE U24_BE S32_LE S32_BE U32_LE U32_BE FLOAT_LE FLOAT_BE SUBFORMAT: STD SAMPLE_BITS: [4 64] FRAME_BITS: [4 640000] CHANNELS: [1 10000] RATE: [4000 4294967295) PERIOD_TIME: [25000 300000] PERIOD_SIZE: [100 1288490189) PERIOD_BYTES: [50 4294967295) PERIODS: (0 12884902) BUFFER_TIME: [1 4294967295] BUFFER_SIZE: [100 1288490188] BUFFER_BYTES: [50 4294967295] TICK_TIME: 4000 Sample format not available for playback: Invalid argument Setting of hwparams failed: Invalid argument Is the driver saying it can do format S16_BE somewhere, but fails when the format is actually set? How can I dig deeper on this? Thanks in advance for any ideas! , John
