Subject: usbaudio won't do 24-bit or 32-bit i/o, and won't do 96000 frames per second
Date: Thu, 05 Dec 2002 06:31:29 -0500 [thread overview]
Message-ID: <3DEF3911.4060206@monmouth.com> (raw)
In-Reply-To: <3DEF2ED7.7000808@monmouth.com>
==== This is a slightly-updated clone of item
#636946 on the sourceforge bug/patch reporting
system. I'm moving it to here (the alsa-devel
mailing list) at the request of Jaroslav. ====
I bought an Extigy, which is capable of 24-bit i/o. It is
also capable of digitizing 96000 frames per second.
The problem is, the alsa usbaudio driver seems to know
nothing of such capabilities.
I tried modifying the driver source, in analogy to the dummy
driver, but to no avail.
This means I am unable to use ALSA for this application.
Request #1: USB driver supporting 24-bit i/o. I don't care
whether it is encoded as S24_LE or S32_LE, just so long as
all the bits are encoded somehow.
Request #2: USB driver supporting 96000 frames per second.
Suggestion: If the code had better comments and
documentation, it would be easier for folks like me to
contribute fixes to problems such as this.
Note: there are other problems with this driver; see next
bug report.
