记录创建的多个文件 [英] Multiple files created by arecord

问题描述

我使用buildroot和ARMv7处理器的硬流程进行了自定义分发。
一切正常，但....

I've made custom distribution using buildroot, with hard-flow for ARMv7 processor. Everything is working except....

# arecord -D hw:0,0 -fdat -d 5 test.wav

这将创建多个文件。成千上万的。

This makes multiple files. Thousands of them.

-rw-r--r--    1 root     root        958508 Jan  1 00:19 test-01.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-02.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-03.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-04.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-05.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-06.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-07.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-08.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-09.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-10.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-100.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-101.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-102.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-103.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-104.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-105.wav
-rw-r--r--    1 root     root            44 Jan  1 00:19 test-106.wav

以此类推...

如果我通过-d参数。

This happens if I pass -d parameter. Any idea?

推荐答案

问题似乎出现在从 1.0.28 开始的ARM体系结构上。 c $ c> arecord 版本（ arecord --version ）。
在运行Raspbian Jessie的Raspberry Pi 3上，我设法将 alsa-utils 的版本从 1.0.28-1 降级改为 1.0.25-4 （回溯到Wheezy的回购），从而解决了问题：

The problem seems to appear on ARM architecture starting from 1.0.28 arecord version (arecord --version). On Raspberry Pi 3 running Raspbian Jessie I managed to downgrade alsa-utils from 1.0.28-1 to 1.0.25-4 (rolling back to Wheezy's repo), so that fixed the problem:

• sudo nano /etc/apt/sources.list


• 将以下行添加到文件末尾 deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi


• sudo apt-get update


• sudo aptitude版本alsa-utils （这应该显示旧版本成为


• sudo apt-get install alsa-utils = 1.0.25-4


• 现在 arecord --version 应该显示降级的版本 1.0.25


• 您现在可能想要删除添加到/etc/apt/sources.list的那一行，这样就不会从wheezy中获取其他软件包


• sudo nano /etc/apt/sources.list


• 删除行 deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi


• 再次运行apt-get update


• 也将alsa-utils搁置，以免升级


• sudo apt-mark hold alsa-utils

• sudo nano /etc/apt/sources.list
• add the following line to the end of the file deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
• sudo apt-get update
• sudo aptitude versions alsa-utils (this should show the old version to become available)
• sudo apt-get install alsa-utils=1.0.25-4
• now arecord --version should display downgraded version 1.0.25
• You probably now want to remove that line you added to /etc/apt/sources.list, so that you don't get other packages from wheezy
• sudo nano /etc/apt/sources.list
• remove the line deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
• run apt-get update again
• also, put alsa-utils on hold so it doesn't get upgraded
• sudo apt-mark hold alsa-utils
