[alsa-devel] [PATCH 1/2] alsa-info: Make sure all full script is run even with "output" option
by David Henningsson 22 Aug '14

22 Aug '14

For some reason, when the --output option is used, less information is included compared to when no options are used. This is unexpected. Fix this by running "withall" also when the output option is used.

[alsa-devel] trouble using S/PDIF input on CMI8738-MC6: C-Media CMI8738 (model 55)
by jon 22 Aug '14

22 Aug '14

Greetings, I hope I have sent this email to the correct list, I apologize if I am in error. I have a somewhat antiquated motherboard (SOYO SY-K7V DRAGON Plus!) with an on-board soundcard using the cmipci driver. Audio playback through the analog output jacks works, as does audio capture from the analog line-in jack. I really would like to get either of the digital inputs to work for recording instead though (it has both optical and coaxial input *and* output jacks available on an optional breakout connector) however I have so far been unable to do so for either the coaxial or optical inputs even after having tested several different cables and external devices as audio sources. Neither recording nor the "monitor" feature of either digital inputs works. Unfortunately though I have no means by which to test the digital output other than to look into the end of a connected toslink cable and verify it indeed lights up. Initially I suspected my alsamixer settings were simply wrong, however after extensive testing and searching I have begun to suspect that the driver is simply not properly recognizing the optional (apparently somewhat rare) extra i/o expansion header. When I try to record from the digital input device, arecord outputs the status text, pauses for a few seconds and then spits out an i/o error. Below, in sections divided by the "####" bars I have included what I hope is enough relevant information for someone knowledgeable to help me troubleshoot/fix this issue. If information is missing I will happily provide it given instructions on how to find it. ######################################################################## Here is the arecord output: $ arecord -v -v -D hw:0,2 -f dat test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Hardware PCM card 0 'C-Media CMI8738' device 2 subdevice 0 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 16384 period_size : 4096 period_time : 85333 tstamp_mode : NONE period_step : 1 avail_min : 4096 period_event : 0 start_threshold : 1 stop_threshold : 16384 silence_threshold: 0 silence_size : 0 boundary : 1073741824 appl_ptr : 0 hw_ptr : 0 arecord: pcm_read:1801: read error: Input/output error ######################################################################## In case its relevant, here is the contents of the cmipci registry file before I run arecord: ~$ cat /proc/asound/card0/cmipci C-Media CMI8738 (model 55) at 0xd000, irq 11 00: 02 00 00 00 04: 12 e0 00 00 08: 0c 00 09 00 0c: 00 00 00 08 10: c0 00 00 00 14: 00 00 00 00 18: 00 01 81 0a 1c: ff ff ff ff 20: 10 40 08 00 24: 00 01 00 00 90: 20 09 00 10 And here is its contents while arecord is "hanging" - after I start the arecord command but before it spits out the i/o error then exits: $ cat /proc/asound/card0/cmipci C-Media CMI8738 (model 55) at 0xd000, irq 11 00: 02 00 02 00 04: 12 e2 00 00 08: 0c 00 09 00 0c: 00 00 02 08 10: c0 00 00 00 14: 00 00 00 00 18: 00 01 01 0a 1c: ff ff ff ff 20: 10 40 08 00 24: 00 01 00 00 90: 20 09 00 10 The second contents are the same as while its successfully recording from the analog input. After the i/o error it reverts to the previous contents, but the output is always a silent file of exactly 44 bytes which I assume to be the minimum size for an empty PCM WAV file. ######################################################################## And, last but not least, here is the output of the alsa-info.sh test script which I hope will contain everything else relevant. Note that While the current kernel is version 3.12 (vanilla) with both the "#if 0" lines in the cmipci.c file changed to "#if 1", the behavior as I have tested it is basically unchanged with the exception of the appearance of some more S/PDIF switches in alsamixer, and also unchanged from the stock wheezy 3.2 kernel. upload=true&script=true&cardinfo= !!################################ !!ALSA Information Script v 0.4.63 !!################################ !!Script ran on: Tue Aug 12 15:22:29 UTC 2014 !!Linux Distribution !!------------------ Debian GNU/Linux 7 \n \l PRETTY_NAME="Debian GNU/Linux 7 (wheezy)" NAME="Debian GNU/Linux" ID=debian HOME_URL="http://www.debian.org/" SUPPORT_URL="http://www.debian.org/support/" BUG_REPORT_URL="http://bugs.debian.org/" !!DMI Information !!--------------- Manufacturer: VIA Technologies, Inc.

[alsa-devel] usb-usx2y: playback fails with Tascam US122 on kernel 3.14
by Dr Nicholas J Bailey 21 Aug '14

21 Aug '14

I am having trouble with the US122 in playback and duplex mode. In capture mode, it is working. This problem occurs on (at least) Linux arial 3.14-1-686-pae #1 SMP Debian 3.14.7-1 (2014-06-16) i686 GNU/Linux I note that my computer uses the much-maligned Intel Corporation 5 Series/3400 chipset (rev 05), but I have a UK£12 5.1 out/2.0 in audio adaptor which works in either capture or playback (although not in duplex). Also, booting an old kernel: Linux arial 3.2.0-4-686-pae #1 SMP Debian 3.2.57-3+deb7u2 i686 GNU/Linux or Linux arial 3.10.11 #1 SMP Wed Oct 2 19:26:59 BST 2013 i686 GNU/Linux both seem to support full duplex operation. This is therefore a regression between 3.10.11 and 3.14-1 (at least, something on my system has regressed and I am suspecting the usx2y module). dmesg tells me: [ 2873.134973] usb 2-1.6: new full-speed USB device number 9 using ehci-pci [ 2873.228117] usb 2-1.6: New USB device found, idVendor=1604, idProduct=8006 [ 2873.228122] usb 2-1.6: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 2873.447646] usb 2-1.6: USB disconnect, device number 9 [ 2875.183348] usb 2-1.6: new full-speed USB device number 10 using ehci-pci [ 2875.277235] usb 2-1.6: New USB device found, idVendor=1604, idProduct=8007 [ 2875.277240] usb 2-1.6: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 2877.844821] cannot submit datapipe for urb 0, err = -28 ... this message repeated many times ... [ 2877.912388] cannot submit datapipe for urb 0, err = -28 [ 3528.609688] active frame status -18. Most probably some hardware problem. I used to use these interfaces with jack in duplex mode, but this is no longer possible. Running up audacity for a test, capture from the US122 works fine, but once the US122 is selected for playback, audacity pops up an "Error opening sound device". Further attempts to record (even capture-only) result in corrupted, high-amplitude noise. Nick/. Other info which might help (a bit noisy, because I'm not sure exactly what's wrong) follows.

[alsa-devel] can't insmod patched snd-usb-audio
by Orm Finnendahl 21 Aug '14

21 Aug '14

Hi, hope it's ok to post it here as it's not (yet) official alsa: After having no issues with Tobias Hoffmann's scarlett alsa mixer patch on my older kernels, trying to insmod the patched kernel modules on my most current kernel (the patch and documentation obtained with "git clone http://github.com/trrichard/alsa-driver_scarlett.git") fails with the following message: root@x1-orm:/usr/src/linux-source-3.14# insmod sound/usb/snd-usbmidi-lib.ko insmod: ERROR: could not insert module sound/usb/snd-usbmidi-lib.ko: Unknown symbol in module root@x1-orm:/usr/src/linux-source-3.14# insmod sound/usb/snd-usb-audio.ko insmod: ERROR: could not insert module sound/usb/snd-usb-audio.ko: Unknown symbol in module I'm on debian testing with 3.14-2-amd64 kernel and followed all the instructions in the scarlett kernel patch README (I tried three times each with a fresh kernel source tree from scratch to be sure). The patch has worked for me on older kernels without any problems. Does anybody know how to deal with this? Let me know if you need further information. Yours, Orm

[alsa-devel] ALSA - Channel swap
by Tomas Matejka 20 Aug '14

20 Aug '14

Good afternoon, i have a problem: I use sound codec CS4202, which I control with AT91SAM9263. I'm using ALSA sound library. When i use CAPTURE mode, sometimes it swaps left and right channel. I have found this discussions on Internet, where is described similar problem: http://pl.it-usenet.org/thread/17996/3593/ http://sinustrom.info/2013/03/21/atmel-soc-ssc-channel-swapping/ I have figured out, that the problem could be in driver or in ALSA library. Have you any solution ? Did you encountered similar problem ?

[alsa-devel] buffer time
by Joël Krähemann 20 Aug '14

20 Aug '14

What's the correct buffer time to use with alsa? since I have following in ags.sf.net buffer size: 940 alsa iterations: 47 per second Since I don't have segmentation of tact in my application BPM is the only scale I got really slow output. Further can't run anymore with realtime priorities. I would prefer using 940 because its near a good throughput rate. Years ago I calculated it the exact value would be something 93.whatever Please help best regards Joël
