Hi Jay,
The RFC v3 patches.
BeBoB/OXFW driver in RFCv3 includes some bugs.
Please use latest patches: https://github.com/takaswie/sound Or backport package for Linux 3.11/12/13. https://github.com/takaswie/snd-firewire-improve
- PreSonus Inspire1394
[hack@precision ~]$ cat /proc/asound/card3/#formation [hack@precision ~]$ cat /proc/asound/card3/#clock [hack@precision ~]$ cat /proc/asound/card3/#firmware
OK. I can confirm BeBoB driver detect inspire1394 correctly.
[hack@precision ~]$ arecord --verbose -D plughw:3 /tmp/test.wav [hack@precision ~]$ aplay --verbose -D plughw:3
It looks good.
I guess: - BeBoB driver in RFCv3 has a bug in access by several processes: http://sourceforge.net/mailarchive/message.php?msg_id=31924100 - When PulseAudio was installed your system, PulseAudio generate much access to detect inspire1394. - As a result, BeBoB driver works badly, often hungs your system.
- FireWave
[hack@precision ~]$ cat /proc/asound/cards [hack@precision ~]$ hexdump -C /sys/bus/firewire/devices/fw3/config_rom
For 'struct snd_card.shortname', OXFW driver pick up model name from config_rom. In this case, the model name is 26 bytes (Griffin FireWave Surround). But OXFW driver keeps char[24] (char model[32] in name_card()). So the name is split.
I pushed fix for this issue: https://github.com/takaswie/snd-firewire-improve/commit/cf4cec651de539e5debb...
But this long model name also affects 'struct snd_card.longname' (Griffin Technology Griffin FireWave Surrou (OXFW970 0104), GUID 001292060052048). This shold have been 'Griffin Technology Griffin FireWave Surround (OXFW970 0104), GUID 001292060052048 at fw1,0. S400'. I'm under consideration about how to fix this...

This is a bug of OXFW driver in RFCv3. I already fix this.
Let me know if there is any other information you need.
I want you to test latest patches with FireWave to check regression.
Thank you
