[alsa-devel] [Q] playing / recording mono on a stereo-only hardware
by Guennadi Liakhovetski 30 Jan '10

30 Jan '10

Hi I know this question belongs rather to alsa-users, and I did ask it there, but got no solution so far. Maybe someone here can help. The recently posted SuperH SIU driver only supports stereo playback and capture (channels_min = channels_max = 2). Is there a way to tell alsa-lib to duplicate the mono-channel during playback and to mix recorded channels (or use one of them), if mono recording is requested? Thanks Guennadi --- Guennadi Liakhovetski, Ph.D. Freelance Open-Source Software Developer http://www.open-technology.de/

[alsa-devel] [PATCH 4/5] Echoaudio - add suspend/resume support
by Giuliano Pochini 30 Jan '10

30 Jan '10

4/5 Add suspend support #2: This patch adds suspend and resume callbacks. It also rearranges parts of the initialization code so it can be used in both the first initialization (when the module is loaded we also have to load default settings) and the resume callback (where we have to restore the previous settings). P.S. I'll fix "rettings" later. Short description: This patch adds rearranges parts of the initialization code and adds suspend and resume callbacks.

[alsa-devel] [PATCH 3/5] Echoaudio - add suspend/resume support
by Giuliano Pochini 30 Jan '10

30 Jan '10

3/5 Add suspend support #1: This patch moves the code that initializes the card's controls with default valued from the init_hw() function into a separated set_mixer_defaults() function (one for each of the 16 supported cards). This change is necessary because during resume we must resurrect the hardware without losing the previous settings. set_mixer_defaults() must be called only once when the module is loaded.

[alsa-devel] [PATCH 2/5] Echoaudio - add suspend/resume support
by Giuliano Pochini 30 Jan '10

30 Jan '10

2/4 Add firmware cache #2: This patch changes get_firmware(), free_firmware() and adds free_firmware_cache(). The first two functions implement a very simple cache and the latter is used to actually release all the stored firmwares when the module is unloaded. When CONFIG_PM is not enabled those functions act as before, that is free_firmware() releases the firmware immediately and free_firmware_cache() does nothing. Short description: This patch implements a simple cache for the firmware files when CONFIG_PM is defined.

[alsa-devel] [PATCH 1/5] Echoaudio - add suspend/resume support
by Giuliano Pochini 30 Jan '10

30 Jan '10

1/5 Add firmware cache #1: When CONFIG_PM is enabled the firmware cannot be released because the driver will need it again to resume the card. With this patch the firmware is passed as an index of the struct firmware card_fw[] in place of a pointer. That same index is then used to locate the firmware in the firmware cache.

[alsa-devel] A driver for Zoom R16 (USB)?
by Jani Frilander 30 Jan '10

30 Jan '10

Hi. I have a Zoom R16 multitrack recorder / USB audio interface / control surface unit. Unfortunately it's audio interface/control surface part currently don't work with linux. When I plug it in kernel (2.6.31-9-rt) won't recognize it as a audio interface. Is there a way to make it work? It probably needs to be hacked, because Zoom won't provide any technical information, according to their email I received. I'm a total newbie in driver development, but I'll be willing to work with this. Regards, Jani Frilander

Dear ALSA Dev-Team, while testing my driver, I figured out that under some circumstances there occur overruns when recording two streams: first I startet a long capture at device 1: -bash-3.2# -bash-3.2# arecord -D hw:0,1 -d 180 -r 32000 -c 1 -t wav -f S16_LE arecord_049.wav Recording WAVE 'arecord_049.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono overrun!!! (at least 121.536 ms long) overrun!!! (at least 115.361 ms long) overrun!!! (at least 190.883 ms long) overrun!!! (at least 121.772 ms long) overrun!!! (at least 119.487 ms long) In another terminal, I started a second capture on the second device. Everytime this capture is done, I got an overrun in the first capture (see above) -bash-3.2# -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# It seems, that the duration of the overrun relates to the capture time of the second capture, as it increases with bigger capture times. But if capture times are bigger than 25s, it seems there is no overrun...just some logs to clarify: First Terminal: -bash-3.2# -bash-3.2# arecord -D hw:0,1 -d 180 -r 32000 -c 1 -t wav -f S16_LE arecord_049.wav Recording WAVE 'arecord_049.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono overrun!!! (at least 99.074 ms long) Second Terminal: -bash-3.2# -bash-3.2# arecord -D hw:0,0 -d 30 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 30 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 30 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 15 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# First Terminal: -bash-3.2# arecord -D hw:0,1 -d 180 -r 32000 -c 1 -t wav -f S16_LE arecord_049.wav Recording WAVE 'arecord_049.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono overrun!!! (at least 193.656 ms long) Second Terminal: -bash-3.2# arecord -D hw:0,0 -d 25 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# arecord -D hw:0,0 -d 20 -r 32000 -c 1 -t wav -f S16_LE arecord_047.wav Recording WAVE 'arecord_047.wav' : Signed 16 bit Little Endian, Rate 32000 Hz, Mono -bash-3.2# So I am wondering why such an overrun occurs, can someone please give me some hints what my be the reason? Thanks in Advance! Tobias

[alsa-devel] [PATCH 0/2] McBSP: OMAP3: Add sidetone feature
by Ilkka Koskinen 29 Jan '10

29 Jan '10

The first patch implements McBSP sidetone feature on OMAP3 while the second one provides ALSA interface for using it. The patch set is based on the patch Eduardo Valentin sent to alsa-devel mailing list in October 2009. Channel gain control and enabling the sidetone have been moved to ALSA interface as suggested in comments.
