Re: [alsa-devel] [FFADO-devel] Call for testing: ALSA driver for Fireworks/BeBoB based devices

Hi all,

This is a call for testing my ALSA driver for Fireworks/BeBoB based devices.

Please test 'snd-fireworks' for Fireworks and 'snd-bebob' for BeBoB if you have some devices listed in the end of this mail.

Status:

• still under development
• Without snd-dice and Clemens' development (I must do this later)

Functionality:

• playback/capturing (full duplex) with PCM/MIDI interface
• hardware metering for some devices with CONTROL interface
• switching clock source/digital interface/digital mode with CONTROL

interface

• print hardware status with PROC interface

Note:

• Don't use simultaneously 'ALSA PCM/MIDI playback/capture' and 'jackd

with Firewire (FFADO) backend'. Both of them try connecting to the device when another is running.

• I add much modification into snd-firewire-lib for full duplex

synchronization of receive/transmit AMDTP stream.

Requirement:

• Linux kernel 3.11 or later because of Juju (nickname of Firewire

stack) changing its API.

• Dynamic Kernel Module Support (DKMS) is reccomended for safely

installing/uninstalling (I work with Ubuntu 13.10)

Bug report:

• report with /proc/asound/cardX/#XXX
• please send your experiences to me with the output

How to install (DKMS):

1. $ git clone https://github.com/takaswie/snd-firewire-improve.git
2. $ ln -s $(pwd)/snd-firewire-improve/ /usr/src/alsa-firewire-3.11

(superuser) 3. $ dkms install snd-firewire/3.11 (superuser)

How to uninstall (DKMS):

1. $ modprobe -r snd-bebob snd-fireworks snd-firewire-lib (superuser)
2. $ dkms remove ans-firewire/3.11 --all (superuser)
3. $ rm /usr/src/alsa-firewire-3.11 (superuser)
4. $ rm snd-firewire-improve

How to install (Manual):

1. $ git clone https://github.com/takaswie/snd-firewire-improve.git
2. $ cd snd-firewire-improve
3. $ make

4, backup system snd-firewire-lib/snd-firewire-speakers/snd-isight (superuser) 5. install snd-firewire-lib/snd-firewire-speakers/snd-isight/snd-fireworks/snd-bebob (superuser) 6. depmod -a (superuser)

How to uninstall (Manual)

1. modprobe -r snd-firewire-lib snd-firewire-speakers snd-isight

snd-fireworks snd-bebob (superuser) 2. remove snd-firewire-lib/snd-firewire-speakers/snd-isight/snd-fireworks/snd-bebob (superuser) 3. recover snd-firewire-lib/snd-firewire-speakers/snd-isight (superuser) 4. depmod -a (superuser)

Hi Takashi,

Today I finally had some time to try your patches. I have a Terratec Phase 24FW Card. I did use the latest version (as of today) from https://github.com/takaswie/snd-firewire-improve.git on a Debian testing system. I did not use dkms but loaded the driver manually: $ cd sound/firewire $ modprobe -r snd-firewire-lib $ insmod ./snd-firewire-lib.ko $ insmod ./bebob/snd-bebob.ko

First I have to say the driver does work and I can play music through the device, so thanks for your work. Unfortunately I managed to crash my system with it. I was using mplayer2 to play sound files and it seems that if I let mplayer2 play multiple files the system crashed somewhere between the end of the last file and the start of the new file (probably a race or something). I only did some quick testes because I hat to reboot after every crash (even sysrq doesn't work anymore), but I think the crash doesn't happen every time mplayer2 switches to the next file, but most of the time. If I let it play only one file I didn't observe any crashes.

Here is the mplayer2 command I did use for testing: $ mplayer -ao alsa:device=hw=1 <some files>

And here the output of /proc/asound/cardX/#XXX $ cat /proc/asound/card1/#clock Sampling rate: 48000 Clock Source: Internal $ cat /proc/asound/card1/#firmware Manufacturer: bridgeCo Protocol Ver: 1 Build Ver: 0 GUID: 0x000AAC04005F9C07 Model ID: 0x04 Model Rev: 1 Firmware Date: 20060420 Firmware Time: 105241 Firmware ID: 0x4 Firmware Ver: 18681119 Base Addr: 0x20080000 Max Size: 1572864 Loader Date: 20040719 Loader Time: 134002 $ cat /proc/asound/card1/#formation Output Stream from device: Rate PCM MIDI 22050 0 0 24000 0 0 32000 4 1 44100 4 1 48000 4 1 88200 4 1 96000 4 1 176400 0 0 192000 4 1 Input Stream to device: Rate PCM MIDI 22050 0 0 24000 0 0 32000 6 1 44100 6 1 48000 6 1 88200 6 1 96000 6 1 176400 0 0 192000 6 1

Attached is the crash log as far as I could obtain it.
