[PATCH v2 0/2] snd-usb-6fire: firmware load and pulseaudio assumption
by René Herman 21 Jul '20

21 Jul '20

Hi Takashi. v2 of the earlier today sent out "set" for snd-usb-6fire, although now only two patches left, incorportaing the requested changes. The snd-usb-6fire driver for the TerraTec DMX 6Fire USB soundcard has been failing its firmware upload due to a non DMA-capable buffer on the stack. First of the patches kmallocs said bufffer instead and fixes the firmware upload; also makes it more alsa-generic by using the "goto out" structure. Note that it only looks a bit ungeneric as a patch due to also needing to at the same time unify its failure path: it's obvious when looked at post-apply. After that first patch the driver nominally works again but still has Pulseaudio crap out due to struct snd_pcm_hardware.channels_min=1 causing it to recognize it as a mono device only. Comparing with e.g. the TerraTec Aureon 7.1 Universe driver it seems that the solution is to simply set channels_min=2 as per the second patch. With these changes the card works again. Driver author Torsten Schenk has seen these and is fine with them: maintains an external driver with more options. I or he might time permitting start integrating more into the kernel driver over time.

[PATCH 0/3] snd-usb-6fire: firmware load and pulseaudio assumption
by René Herman 21 Jul '20

21 Jul '20

Hi Takashi. I sent these out a week ago to alsa-devel (only) but am not sure they got anywhere, perhaps due to at least the alsa-devel archive scrubbing the text/x-patch attachments as "non-text". The snd-usb-6fire driver for the TerraTec DMX 6Fire USB soundcard has been failing its firmware upload due to a non DMA-capable buffer on the stack. First of the patches kmallocs said bufffer instead and fixes the firmware upload. After that first patch the driver nominally works again but still has Pulseaudio crap out due to struct snd_pcm_hardware.channels_min=1 causing it to recognize it as a mono device only. Comparing with e.g. the TerraTec Aureon 7.1 Universe driver it seems that the solution is to simply set channels_min=2 as per the second patch. Third patch unmarks the snd_pcm_hardware struct const as it it is in fact changed in usb6fire_pcm_open(), even though through a pointer, and is supposedly trivial. With these changes the card works again. Driver author Torsten Schenk has seen these and is fine with them: maintains an external driver with more options. I or he might time permitting start integrating more into the kernel driver over time.

Reference USB card driver?
by René Herman 21 Jul '20

21 Jul '20

Good day. I recently acquired a TerraTec DMX 6Fire USB card to play with, which works after one/two just to alsa-devel sent out patches. Not very good though; it's for example rare to not have my music skip when Pulseaudio mixes in the "there's new mail" sound from Thunderbird. I haven't been around here for a very long time now but have some ALSA-experience with ISA and PCI hardware from long ago. None with USB whatsoever though. Is there a reference/best-practices USB card driver that I can/should look at? Regards, Rene
